Hi all,
I know this issue has been kicked to death but I'd like to get some opinions. I've searched and read through numerous threads about the tp2's battery and some are extremely happy with their battery life while others are not.
Just today I was talking on my tp2 for 5 mins and the battery went from 98-99% to 91%. This was around hr after I had unplugged it from a 7hr recharge (went from 50% to 100%). This would mean I have a talk time of 50-60 minutes, which doesnt seem right.
Typically, I get down to 40-50% in a day after heavy data usage (google maps, internet browsing) with no phone usage.
I've installed maybe 10 tweak cabs/programs and I've made sure s2u2's display mode is set to rawbuffer.
Thoughts?
Is your battery/device new? The battery needs a couple recharge cycles to reach optimal capacity...
have had it for 4 weeks now. Are we talking about 0 to 100% when you talk about recharge cycles?
I wouldn't worry too much. I find that when the battery capacity is above 90%, the readings are not very accurate. I've sometimes experienced a drop of 6 or 7 percent over a span of a few minutes and sometimes, it's stuck on 99 or 98 percent for an hour of usage.
I use my device heavily during the day and it gets down to about 40% at the end. So, that's pretty much in line with what you experience.

Since i seem to be experiencing battery drain more then i think i should.
I was thinking, since i installed the 1% bat driver, its almost as if i can SEE the drain happening...and maybe its psycological?
Perhaps seeing it go down 1% every 10 minutes makes us, or me, think there is a super drainage issue, vs 10% every 30 or 40 minutes.
opinions?
I get basically the same usage out of my phone. On days that I am playing with the ROM, tweaking, and generally screwing around with the phone, I usually have about 30% or so when I go to bed (usually awake and phone unplugged for about 18-20 hours). When I just use it as a device, as a normal person would, I usually have about 60% left when I go to bed, on the same time scale.
When I woke up this morning, I turned off my phone and after it booted up I unplugged it, because I wanted to get a realistic idea of it's battery life (it's been fluctuation on me). It was at 100% I'm reading at 19% now, I have an Up time of 3:12:00 and an Awake time of 2:44:16 (I have been using it pretty constantly, so the awake time doesn't worry me too much). This is obviously ridiculous, this could possibly die in less than 3 & 1/2 to 4 hours. Battery use is: Android System: 58%, Display: 17%, Cell standby: 14%, Everlands Lite: 6%, Phone idle: 3%, android.process.acore: 2%. I just downloaded Everlands today and played it a lot, but with that low of a percent it can't possibly be an issue. I'm running Damage Control v3.2, and I'll post the DConfig in the next post.

Please, any explanation for why my battery drain has suddenly jumped up so much would be greatly appreciated!
did your battery suddenly start dying quick? mine will last all day ONLY if i leave it alone all day, no calls or anything. If I use it minimally i get about half a day and if I have heavy usage on it then I get about 4 hours or so.
Prior Battery Life
I was able to go about 17 hours off the charger once without holding back on my usage at all, and that wasn't a huge outlier. Seriously, I know I've been able to get at LEAST 12 hours out of it streaming Pandora for an hour plus lots of texting, twitter, facebook, web browsing, and even moderate GPS usage.
I think other battery threads would be more useful if they included Awake time more often, because obviously I am not having a problem with it not going to sleep (since I was actually using the thing almost the entire time I had it off the charger).
You may actually have a bad battery. Mine gets unplugged at 6am, has a 30 min charge at 8pm on my way home in the car, then plugged in at 11:30 or 12 with 40% left.
The only thing I have done is kill most of the widgets, use a static background and that is about it.
you might have a bad battery, or maybe it was just something for that time. if it keeps happening, go back to sprint and they'll probably give you another battery or even phone (assuming they have them in stock)
Battery Defect?
I tried the method that one user supposedly learned from HTC ( I can't post a link but it's titled "Official response from HTC RE: How to double battery Life (WORKS!) + 2nd Reply" ), and I'm not sure I've gotten the same battery life out of it since that happened. I just got it charged back up to 100% now, I'm going to try upgrading to Damage Control v3.2.2.1 and I'll throw it into the Power Save mode in the DConfig, then see how long it lasts.
I've had the phone since Sept 6th and this is 4th day I have my phone.
My battery life has been draining like crazy. I don't have a data plan, but I do go on wifi sometimes (not very often, and I don't keep it on for long). Maybe in total an hour to two a day.
I wouldn't say I am a heavy user, I don't play any games or watch any videos nor listen to music at all. I only sms and download apps.
It's been 5h 42m 35s since unplugged and my battery life is down to 57. I hardly use it, my settings are pretty much the lowest.
It says
Android System 40%
Cell standby 21%
Phone idle 13%
Display 12% (weird, since I have animations are turned off and I used lowest brightness)
Camera 6% (I took 3 photos)
Wifi 4%
Maps 2%
Dialer 2%
about 2 hours ago, I rooted my desire since I've read reviews that it makes it faster, prolongs battery life and what not. (plus I could do so much more with it later on). But my battery was still draining at like 1% every minute and half that I touch it. (I also have task killer, but I don't kill task very often)
Then my friend suggested I get SetCPU (which I did) around 2 hours ago after I rooted my phone. Then I went out and hardly touched the phone unless I received sms, or to check the time. And it went from like 69 to 56 (within that 2 hours of doing nothing)
I've searched the forum for extending battery life (and googled as well) and read other users who have the same problem, and I pretty much did what was recommended but it's still draining.
I can hardly make it through the day!!
Is there any other way that I can charge it (when to charge it) or.. do you think it might be my battery's problem? Should I buy a new one?
Thanks for all the help again (I know this kind of thread has already been done, but that was in like April)
Your battery takes time to settle if it's a brand new device. It takes a few charge/discharge cycles for that.
If after say 14 days you are still getting poor life I'd try calibrating it. Instructions are HERE.
thanks! i will try that if my battery life still drains this crazily in a week.
Ok so after a hard reset and at 100% charge my HTC Radar says 1 day and 15 hours remaining. It has been like that for a few days. After about a week, 100% charge results in 20 hours remaining life. Eventually after a few more charges it averages at 15-17 hours remaining battery life. That is a big worrying decrease. These figures are always noted after a 100% charge and leaving it to settle for a bit.
So I started thinking what could be causing this decreasing stand by time?
Two theories:
1. It must be an app as I got excellent stand by time from a hard reset and with no additional apps so maybe a particular app is playing with the battery meter?
2. Could it be leaving the phone over night plugged in is doing something to the battery? Maybe I should unplug it as soon as it gets to 100%?
The strange thing is it can't be the actually battery degrading over time as the phone is new. Also, I have recently flashed a custom ROM to my Radar at a point when stand by time was at 15 hours at 100% and after the flashed ROM the standby time went back up to 1 day and 15 hours. Something is not right. It must be an app.
Any other thoughts/theories or anyone else in a similar situation?
Discuss please so we can all learn something to hopefully solve this problem for other handsets too!
My guess: calibration. The system estimates your runtime based on previous runtimes, that's why it's getting lower. Did your phone actually ever run that long, btw?
yes it did. very very close. i was amazed.
and does it now actually run out faster? I have noticed this on my ipod. It used to tell me 1h battery remaining and it would run for another 3h until i got home and another 2h the next day (when I noticed I forgot to charge). Also, are you using your phone more now? The biggest battery drain is the display.
Remaining battery life is estimated as follows:
Immediately after being removed from the charger is based on previous usage charging.
After this time estimate is based on current consumption.
In the first week after hard reset or install ROM the period are recorded in the system.
After a year of use of personal phone (HD7) and trying different rom and different settings for gps, 3g, edge, and light i found that the consumer eating large battery . After a more detailed study will say that is the main consumer.
Thanks for your comment Ovi but this is not about how the consumer is wasting the battery by usage. The question I raised was about how the standby time varied at 100% after a hard reset and after weeks of usage at 100%. The stand by time decreased without using the phone after a full charge. That is what is puzzling me. In theory it should be the same stand by time no matter how long the phone has been owned and the rate of discharge is due to usage - agreed.
Hello all,
I bought a new Z play to replace my ageing phone, and I have mixed feelings about the battery life. The phone has received universal praise for its battery life, and while some of it is true in my case, I can't seem to get those high SoT numbers that everyone brags about.
It's very difficult for me to break the 6h SoT barrier, and I consider myself a light user: whatsapp, browsing, some reddit, and the occasional music (through headphones). I don't play any games, or perform heavy tasks. Also the phone is connected to WiFi 85% of the time, get decent signal, and the screen is set on auto-brightness.
Running latest version of the stock rom, and I performed factory reset + wiped cache + reset network settings countless times as per suggestions.
Attached some stats for 50% that I just took.
Is there something I'm missing?
Take it with a grain of salt, just because people brag about numbers does not mean they are real or obtainable by everyone. Battery life will vary for every user and phone. The time you have is in the acceptable range and I would not worry.
Yes, even I have never achieved the 8-9+ hrs of SOT that's I've seen in some threads. Based on my usage I get a minimum of 6.5hr SOT with the phone lasting a good 25-27 hours before I have to plug it back in.
Since the phone is new it might take a few cycles for the battery to truly show its stamina.
Those answer are definitely right. It all varies on the users. . Also please makes sure you have bluetooth and wifi scanning off. (Location> Scanning > Bluetooth & Wifi Scanning) Another factor is apps. Get rid of facebook and facebook messenger. Apps that use GCM eat battery like a range rover eats gas. I've hit 8--10 hr of SOT before. Let your phone get use to your daily activities. I believe it'll optimize itself over time.
It's normal.
I was also getting earlier 5-6 hrs SOT(When the device was new) but not I'm getting 8-9 hrs SOT.
So as your phone is new it might take few cycles for the battery to show its full stamina!
Cheers!!
Thanks for the replies and for putting my mind at ease.
Bluetooth and wifi scanning are off (forgot to mention that).
Anyway, I understand. Those insane SoT of 10+ are best case scenarios with careful use of the device. Still happy with my current capacity (anything which lasts until the next morning is great).
And yep, the phone manual (who reads those anymore), did mention the battery taking a few cycles before reaching its capacity.
Now, for a different issue. If I'd like to disable turbocharging/quickcharging my phone, would a USB C to A cable coupled with any charger (including the quickcharging ones) do the trick? Based on my understanding, the cable limits the chargining power, so any regular (quality) C to A cable should restore normal charging speeds even when using a fast charging charger. In case you're wondering why I'd like to do that, it's because the phone gets way too hot for my liking when using the Moto turbocharger and I'd like to reserve that for when necessary.
Well, guyz do have a point.
The screenshots are showing you have almost 3hrs SoT after day and a half. This is normal.
Those >10 hrs of SoT aren't achieved with careful usage. Coming from my experience, I got 10.5 hrs SoT with 10% battery left, BUT, in one day. My Moto can last up to 3 day with one charge, but in those 3 days I'll have maybe 4hrs SoT. So, in average, my Moto lasts up to 2 days with 6/7hrs SoT (I mostly use FB, Messenger, WhatsApp, Viber, YT, Instagram, stock 6.0.1). It simply depends how you use it. That big, almost 11hrs SoT, I could only achieve on weekends, coz otherwise I don't have the time to stare in my phone so much.
On that other thing, Moto does get pretty hot while charging. And you're right, the cable does limit the charging power so it will probably work.
I was one of those users getting 10h SoT early on. But I was doing that inside a 24h usage window. Your 50% stats have you stretched out to like almost 3 days off charger. Idle time vs. screen on time is ALWAYS a trade-off.
I look at battery drain in terms of drain rate at idle, and drain rate with screen on. Early on I was seeing 6% drain per hour of screen on, and 1-1.5% per hour screen off. So basically 5 hours of idle time costs you 1 hour screen on. Those were my numbers on the original MM build. My battery life has gotten worse with every software update. I have NOT done a factory reset, mostly because I don't want the hassle and I still get a day off normal use with plenty of battery to spare. But I usually see 18h off charger and 3-4h SoT in a normal day, and that leaves me at 40-50% when I plug in.
Looking at your stats, if screen on costs you 6% per hour, you have 17% worth of screen on drain. That leaves 33% idle drain over 38 hours, or sightly less than 1% per hour idle. Seems pretty darn good to me.
Your cell signal is definitely not helping your battery life. Switch to 2g when on wifi, your signal bar should be full and it'll probably help your battery life.
Enjoy the fact that this phone lets you keep BT/WiFi scanning/Facebook/etc. on without having to worry whether or not you're going to make it a full day. I use all that stuff, have multiple live widgets updating, brightness at least half way, T-Mobile Digits running, and still make it a full day. Additionally, it's great to know that if you do have to make it 2-3 days with minimal usage because you don't have a charger handy, you can. However, I'm willing to bet that 99% of users are able to charge their phone daily. To those users, I say enjoy all the features and don't worry about it.
Really depends on the screen brightness...I can hit those number with my screen brightness turned down a good bit...probably around 30 percent and auto sync off...if i have brightness anywhere above 60 percent then battery life drops a good amount...still well enough to get me through a 12 hour work day but there is a difference
