Battery Performance makes keeping tabs on your Windows Phone look good

Much like screen protectors, we’re not big users of battery apps. Or rather, we found that they were more navel gazing than providing anything truly useful. That’s because battery life on Windows Phone is pretty reliable, where we often don’t have to think about it.

Still, we know these are popular with quite a few of you, so when Battery Performance came to our attention, we figured we’d take a look.

Battery Performance ($1.99) is admittedly one of the nicest looking battery apps for Windows Phone, at least from our limited exposure. It comes with most features we would perceive as being important for keeping you aware of your phone’s status and it does so in an elegant way.

The main features of Battery Performance for Windows Phone 8 are

  • Estimated Talk time
  • Estimated Web surfing time
  • Consumption rate (per hour)
  • Live tile (including double wide)
  • Lockscreen: Detailed status or Quick status
  • Graphs
  • Notifications (battery low, battery charged)
  • Scores from users around the world for comparison

The design of the app is probably the biggest highlight. As you can see from the video tour above, the app presents fluid, elegant animations and an eye-catching Modern UI. While battery apps don’t have a reputation for being easy on the eyes, Battery Performance reminds of some other high quality independent apps on our Windows Phone.

The app, like other battery apps, takes a few days to fully calibrate before it starts to give you reliable estimates on performance. And of course the Live Tile can only update every 30 minutes (a Windows Phone OS limitation). Once it all kicks in though, the app is certainly a solid performer.  

One of the more unique abilities is Notifications, where you can program the app to alert you if your battery falls below a user-defined threshold e.g. 45%. Likewise, you can have it ping you when the battery is fully charged, with both notifications having an optional “night mode” to avoid interruptions in the wee hours.

And no, from what we can tell this does not consume any appreciable battery life, except for the half-hour ping to the Live Tile, which should be negligible (though feel free to correct us if we're wrong; we haven't seen any battery degradation though).

Because of all of that, we have to recommend that you give it a spin, as the app does have a free trial. Indeed, that is probably the only downside of the app: the $1.99 price tag. While we did pay for it due to the high quality of work presented, we can’t help but think it’s a smidge high. Still, with the free trial, we’ll leave it up to you to decide if it is worth it. At the very least, it’s worth your consideration (the app is made by a single indie developer).

  • Good app, love the layout, wish there was an option to have a black background. Keep up the good work!
  • Why will anyone want I app with a black background ? 
  • On a device with an AMOLED screen a black background will use less power. I find them less blinding at night also.
  • yes particularly true for an app named "battery performance". i just bought it, hope the next update will come with black background.
    update: found a bug, it shows 59 on the lockscreen but 58 inside, verified by turning back and forth a couple of times, the number was out of sync.
  • This status will be synchronized at background. We know about this bug and it will be fixed soon. In the next realse.
    About black background, it's not needed now. You will use BatteryPerformance for few minutes not all the time, the most important things is that what type of theme you are currently in use (black or white)
  • What about the Percentage numbers ? when i open the app it takes a bit long to reach its final Number while the Widge shape reaches the correct place almost in two seconds leaving the numbers scrolling behind. if both can be finshed at the same time, that will be great :)
  • This.
  • Guess that answer your question.
  • Interesting. I'm sure gonna give it a try.
  • Most battery apps I use drain the battery more. Without any battery apps installed, my battery on 920 is lasting much longer. I wonder if this app is any different.
  • So true, I don't know why but without any battery app my 920 has more time to live.
  • Been using Battery Sense
    Gonna try this one
  • Me too!
  • I'm still using Battery Sense. This one does seem very interesting but definitely not worth $1.99 when I'm already using a great app.
  • Awesome, i ll try it for free two days then i will plan if i buy it or not
  • Lock screen detail doesn't work
  • We know about it. It will be fix in the next version. Please stay in touch with us!
  • Locked up on my 1020. Re trying.
  • "Battery life on Windows Phone pretty reliable"??? Joke of the day? On my 4th replacement 920 in 8 months and could disagree more. After 4 of them, I'm certain it wasn't just me or rare device issue for poor battery life. I can make it 2-3 weeks after a reset, before battery life goes astray. Get at least a day at first, then slowly dwindle to 6-12 hrs. Headed back to iPhone 5 in a few weeks. Wish the battery was the worst of my woes with the 920.
  • Not sure what you're doing with your phone, so it's hard to judge. I'm not convinced though that Windows Phone has a widespread problem with battery performance and I do hope that you recognize you are in the clear minority here.
  • I really do believe some 920s have battery problems. I had a customer is severe battery problems. He walked in with 18% battery left and within 10 minutes of looking through his settings, it was down to 5%. His replacement also had problems.
  • I don't think WP has a battery problem. I think a lot of 920's do. Until my 920 (on my second one) all my WP's had spectacular battery life. But mine, my wife's, brother and sister in law all have poor battery. Enough so that brother and his wife went back to there iPhones. :( Personally I will take poor battery and WP OS any day over ios but they felt differently.
  • See ya!
  • I have had a 920 since November. I rarely get to the end of the day with less than 40% battery. Maybe your cell provider does something to the phones, or it could be one of your apps?
  • This^
  • It got to be one or several of his apps.
  • Battery life on ATIV S is excellent. Maybe a percentage of early 920's have battery problems, but not windows phone in general.
  • Its only Nokia that has battery issues, we its a 3g reception issue that drains the battery. In flight mode I get 9 hour battery life .
  • having terrible battery and overheating issues since the updates not coming through automatically problem has been fixed by Nokia on my Lumia 920. Sending my phone away tomorrow for a replacement.
  • Yeah mines going back for a repair, they had better return with my data intact as promised.
  • Yeah, I have good days and then there are the "dark days" when I swear there is a little elf in there sprinkling pixie dust draining my battery and just laughing at me. . . Very dark indeed
  • I hear you
  • You mean that 'you couldn't disagree more'
  • You'll be fine with an iPhone 5.... once you slap on one of those external battery covers on it. 
  • Me and my wife and 4 close mates all have 920's and don't have any issues with battery. have you done some reasearch or have you just gone back for a replacement each time the battery dies fast, used the new phone as you did previously and therefore you were just fixing the incident but not the problem? there are plenty of forum articles which tell you how to test or try and improve the battery. have you tried any of those? my battery was draining fast once and i found an article which suggested removing a weather app and then doing a soft reset and since then i haven't had any issues. i barely reset my phone, maybe once a month if that and battery is fine so you're issues may be user related. i have to question why you'd also throw in the "headed back to iPhone 5" comment because those statements, while they may not be necessarily coming from a troll, they certainly do sound trolly.
  • I wouldn't say I have a battery problem but I do wish the battery would last longer. I'm a heavy user constantly on my phone and without charging I can go thru the battery in 4hours or less.
    Good thing I have a wireless charging pad at my desk.
    The issue that I think I have and I'm not sure what's causing it is data... Sometimes I'm at home under WiFi and I still get notifications saying my data is close to it's limit.
    These at&t overages are killing me.
  • The wifi-connection is unfortunately not shown right all the time. Try the app 'active net now!'. This one showes you definitely if you are using wifi or not. Maybe it can help you solving your battery problem also. Excuse my English.
  • Thanks for the info. Let's see if it changes anything
  • I have the same issue. My 920 would get hot and the battery would drain quickly after 10-20 mins of browsing, forcing me to kill all bg apps and turn on the battery saver, even switching to 2g when I'm not at home. Emailed Mr Elop about it and he referred me to a local Nokia Care. I'll see what happens after that.
  • In fact, while I can not call myself a heavy user, i use the phone heavily in spurts, and i have found in those spurts, that the battery drains very very fast. Consider this - it drains 6 percent in 20 min, whenever i am surfing the internet or using Whatsapp. When I play games, the battery drains at 6 percent in 10 min. Now, with similar patterns of usage on my N8, which had i believe 1350mAh battery, as compared to 2000mAh on my L720, my phone lasted a little more than a day, whereas my L720 doesn't last the whole day. I seriously think WP8 is not as power efficient as we are led to believe. At least WP8 is unable to prevent its apps from being power-hungry or huge battery drainers. Therein lies the rub. :(
  • I use a 900 and its battery usually last a day an a half.. My cousins 920 is having alot of problems sometimes it lasts long sometime just a few hours. We are just getting LTE in our area and it seems both our phones are switching between full bars 4g to 1 or 2 bars LTE. Could that effect battery life, do different signals have different power usages?
  • This app is great. Must have been an issue as I was uninstalling the old while installing the nee app. Thanks for the find!
  • One day I'll have a Windows Phone 8 device, but given my luck it'll be 6 months before Windows Phone 9... Sigh
  • There is nothing stabil about battery on WP8.
  • LOLZ
  • To an extent, I agree. My life fluxuates quite radically. Sometimes, I can get more than a day out of my 920. Other times, just a few hours (even a few times while I simply left it unplugged doing nothing). It may be a device specific issue, however, so I cannot generalize and say that all other phones experience the same. From my experience however, there are at least four other people that I know of with Lumia 920's and 8x's that experience the same issues. Maybe GDR2 (which RTM'd in April... this I find completely unacceptable - most consumers won't see an updated slated for April until at least August, but I digress...) will help aid this issue, or maybe even GDR3. I was hoping that by this time of year, we'd be seeing at least GDR3 right around the corner and Blue for November/December but, oh well... Hopefully Microsoft gets the ball rolling with consistent platform updates starting with Blue... Or maybe next year's Windows 9 will be the almighty OS combination of Windows and Windows Phone into one uniform OS. Either way, I support Microsoft but these oddball bugs they're dealing with which are throwing off the update rythm are detrimental to consumer support. As a Microsoft supporter, I have a tough time excusing the extensive waiting periods for updates, when explaining platform issues to others.
  • I agree. That's why I'm dumping my 920 to go back to iPhone 5. Its clear Microsoft has no priority in their mobile platform. Even if they pushed out unbaked updates, they'd be doing something. I wanted to love my 920 and WP8. I'm a Windows technology guy, but for mobile I more need reliable and efficient. I don't love iOS, but I know I can do business if that's the only thing on my person. Since getting 920, I need to always make sure I have my iPad or laptop in order to support my Microsoft infrastructure and applications at my company. Tell me something isn't wrong with that equation.
  • I used to have the same problem with my 810, doing a little tinkering, found out that one or several apps is causing the problem, which app/ apps, I don't know. I uninstalled around 5 of them after that my phone battery is great and my live tiles all works. Maybe you're having the same problem?
  • Windows Technology guy myself and battery life of my Lumia 820 is better then any my collegue's iphones. On a days work averaging 0.5 up to 1% per hour. Twice there was an app misbehaving, but that's it. Check the app that is misbehaving, check for app updates or remove the app and you're good to go.
  • Enjoy your 1440 Mah Battery! (don't believe me check here: lol
  • I did have an iPhone 5 for a week b4 920 came out. Battery life was better. I'm a heavy user, and only ask about 12-14 hours of battery life. Today, I don't think that is too much to ask. At least Mophie makes an exceptional case and still feels less bulky than 920. Strangely, I uninstalled WP Central app, one of a few that I didn't have blocked in background only 1.5 percent drain. Hmmmm.... I've never had that low of drain. 2-3% was norm for first 2 wks after a clean reset, and all the same apps as I've always had installed.
  • Check your background tasks as well. I don't know what app it was but after killing some background tasks for apps I rarely use my battery life went from flakey to consistently lasting a day with moderate usage. Games still seem to heat it up and make it drain quite quickly however.
  • I have about the same apps in WP7 and that worked fine. Most are official apps and why should i need to bother even? If i remove any more apps i destroy the vision what a smartphone are. There are way to many flaws currently. I love what WP wants to be and how it looks, but that doesn't mean i have to accept the flaws it present. Its just sad, and 3 or 4 years down the line i have invested a lot of money in apps and services. But if all the various faults WP8 currently have, don't disappear soon im seriously consider leaving and start over on Android.
  • I agree WP has a lot of potential that it hasn't quite reached yet. WP 8.1 can't come soon enough, but hopefully GDR2 and then 3 will tide me over until then. Right now my 920 is stable, I get good battery and am happy enough and will be patient longer while I wait for things to reach their potential. The alternative of moving back to Android does not exist for me, for it's better app support you have to deal with a very fuzzy and messy system. I find it amusing that people who slagged of Windows Mobile and Symbian actually like Android, cos really it's not all that far removed from them these days. Give Symbian the amount of power the GS4 has and it'd probably be a faster and better OS than Android. Anyway, I'm sticking with WP, if things don't mature by Jan/Feb when I expect to hear news of WP8.1 then i'd consider the dark side (iOS) but I can never see myself returning to Android - unless v5 totally surprises me.
  • +920
  • What is missing if we just "try it"? Can we just continue using it?
  • The version is limited in time
  • @Daniel, try "Insider" battery app it's very nice.
  • It was buggy in my 8x. :)
  • I have on my 810 and 925, and it's runs great.
  • +920
  • Just bought it there, very slick indeed!!
  • Although im not as critical as some other users, I do believe battery life could be improved. I have a lot of live tiles on my home screen, and I really like being able to see notifications without opening each app. However, if I have to limit the number live tiles to conserve battery, I feel like that defeats the purpose. I'm still very happy with wp8, and this battery app has a beautiful interface. Not trying to be rude or negative, just giving my observations. Thanks for the tip :)
  • There's not a day I hit 0% before I charge my 920 but that's because I avoid playing games like Halo on the road. But when I do battery drops quicker than a fly I just swat and isn't very reliable. Games like cut the rope and angry birds hold up fine though. Still questionable.
  • Do you have a Nokia by any chance
