Hello
Just got my blackstone, had it for a few days and i need to charge it every day, almost 2 times a day with moderate use. I turned off 3G, turned down the backlight. But still, if i just mess with it a little, in settings and so on, i can litteratly see the battery life getting lower. An hour ago it was 100%, now its on 83%. Any one who got some pointers on this?
Thanks.
I had a similar issue with mine, got it a couple of weeks ago with a stock Orange UK rom onboard.
Battery hasn't fully depleted, but I usually charge it everynight as it quick charges.
I've since put Dutty's 3.9XT Turbo rom on and battery life has been a lot better.
For example, charged overnight last night (from 59%) and am now at 90% after a few texts and emails. Normally I struggle to hold a 3G signal in my office so its alternating between G, 3G and H all the time, which also drains the battery, and have a push mail application running in the background.
I also charge it in the car in my cradle to and from work. Could probably get two days at a push if I needed to, but it would require charging in the car as well to do that.
Thanks. I flashed it with the energy rom, and the battery really sucks. What does actually the "H" mean, when that is in the status field? "E" is edge, G is 3g, but "H" is?
Try disabling 3g to see better battery life. I think my battry life is quite good without 3g. Running latest energy rom. H is hspda I think. Disable that also to check the affect on battery life.
Thanks. Ive done all that. 7 hours ago the battery was at 100%, now its at 15%. Ive texted 5 messages, and made 2 phonecalls. If i go into settings f.example, press a little, i can see the % gone down a few. Something must seriously be wrong.

Yeah, somethings up with it. To compare I took mine off the charger 7 hours ago sent 4 emails, used gps 3 times, browsed several sites for a total of about 45 min., made two short calls and I'm down to 75%. Thats all on edge.

Definitely sounds like a more serious issue.
I have 3G and HSDPA on all the time and still get through about 25% battery during most of the day, with a few texts, a call or two and some email/browsing etc.
I also make sure that I close any other applications that I've finished with to calm memory and processor usage down.
Thanks. Yes, it sounds like an issue. Wish i had you guys battery. I can litteratly see the % go down, if i go to settings, press something go back and so on. Bought a new 1350mah battery on ebay, hope that would do the trick. Its bugging me sooo much, breaking swet becouse of it, lol.
Did you also turn off bluetooth and wireless? I get three days out of mine without 3G.
Yeah, all that stuff is off. Only edge is on. The battery must be faulty, thats the only thing i can think of. Example, made a phonecall now for 5 minutes, it dropped 10% on the battery.

bthelastman,
Try these following steps to recalibrate your battery.
1) Turn off the phone.
2) Let it charge overnight and don't unplug it.
3) In the morning, use the phone till it is down to 10% (Don't go lower than this number).
4) Turn off the phone, and do a full-charge again.
Repeat these steps 2 ~ 3 times and see if the battery gets better. Sometimes, it is not that the battery is bad, but merely the calibration is a little off. Always try to charge your phone when it is turned off, it keeps the accuracy of the battery lasting much longer without having to do a full-discharge.
Let us know how this works out for you.
Cheers.
Cheers.
Thank you PoisonWolf, i will test this out. Thanks.

akash_nu,
I beg to disagree. What I am saying is, sometimes, the battery in itself can hold the right amount of charge, but the onboard motherboard thinks it is not holding the right amount of charge. The full-discharge helps correct this issue.
If you don't believe me, keep charging your TouchHD whenever it is at 80 ~ 90% for a couple of months and you'll notice a "drop" in how fast your battery drains.
Cheers.
I definitely agree with this.
My Touch HD kept dying after a couple of hours, even when charging it over night. So I turned my phone off and charged it over night with a wall charger (instead of USB) and then it lasted for 48 hours with the same usage.
I think the battery tells the phone it is fully charged even when it is not. So like you say, it just needs recalibrating.
Not sure why the post appeared twice, I only submitted once!
Hi,
The button to the top wright of the phone, to close apps, the screwdriver icon says 59%. I guess that means running 59% of its power of whatever?
Shouldnt it say like 0%, since no apps are running?
Thanks.
After eight months and having my battery give me 2 minutes of talktime on a four hour charge, Orange UK have replaced it for me FOC.

That % shows the amount of free RAM your device has, not how much power it is consuming..
Not sure why you are having this problem, I use BB Connect all day at work and am on the phone for several hours, I don't have 3G in the US but notice if I have WiFI on it drains the battery fast.
Are you sure you don't have a program running that is always looking for the internet? You could try HD tweaks and turn off the internet all together and see if that helps.
My Huawei has a horrible battery life. I'm using stock rom (rooted of course) and the battery drains really fast, like 5-10% an hour even in sleep mode. I have used a battery calibration app recommended by someone here in xda, but I don't think it made any difference. My last Android phone used around 1% an hour, even with data and sync on, but with pretty much the same settings, I can hardly make it through the day with my Huawei.
So, what to do? I don't need the battery to last for days, but having to recharge twice a day at worst is just too much.
My battery drops around 7-10% overnight.
Probably a defective cell?
mine after i installed custom rom (b160) and a battery calibartion in flight mode during my sleep after 7 hours that passed and woke up it was 1% dropped and now 7 almost hours afterwards in normal mode it has dropped 7% with very light use of course...
i want to say just that with gsm active it drained 5% more than in flight mode...
so something must be going wrong , like you don't have a good signal and it uses much power to keep your connection alive and have better signal....
i must say that i have a profile with setcpu when the screen is off with min 122 and max 460...
and just for the record i think that with custom rom also mine was dropping more...
i don't know why although...

Noticed this myself. i use spotify alot on the phone, walking, bicycling, at the gym. and it drains a whole lot of power even in offline mode. but if i set it in flight mode the phone last for hours and hours without even dropping 5-10% of power. but when gsm or data traffic is on the battery life just drains out so quickly! so it is definitly something serously wrong in this rom. Im hoping gingerbread is coming soon to this phone, so maybe all these small issues has been fixed.
I've found highly variable battery life. Sometimes it's awful, almost 50% overnight when it's sleeping on my nightstand, other times it's much better and only drops 7-10% under those conditions.
One thing is Google Maps, even when not in use it seems to suck battery like crazy if it's loaded (and it has a habit of getting loaded even when you don't run it or any apps that use it). There's a long thread on this in the Google support forums, but no sign of a fix from Google yet.
I've found doing a 'force stop' on Maps if it's running often helps, another thing is to reboot the phone after you charge it, that seems to fix it for several days sometimes, but then it starts sucking juice again for no apparent reason, so I tend to reboot it after each recharge. There can also be other apps that due to bugs can suck battery, for a while there app killer did this but the author put a fix out pretty quick and it shouldn't be an issue now.
Just noticed that there's an Android update from Huawei now available for download, maybe that'll fix some of the irritations and help with battery life; I'm off to install it!
where can you find that update? through phone's settings->check for update (in my case it says i got the latest version) or online?
My phone has been on for nearly 48 hours.. charging it right now. I played, connected to wifi, browsed the net, facebook, gmail etc.. and I really played hard on it for a few hours.
30mins ago it switched off, dead battery.. I'm quite pleased with the battery life

Exactly the same problem here. I formatted now both the internal and external SD card, let's see if that helps.
edit: No it doesn't. The problem seems to be that my phone doesn't sleep properly. I charged it to full, then turned the screen off for one hour. App called Spart Parts shows that since last unplugged, time spent without sleeping is 36m.
it took mine 2 weeks to get to the full battery life. now i get 36-48 hours from it.

After 5 weeks i get about 12hrs. No GPS, no 3G. About 10min ago i took the charging cable off. Now Battery History in Spare Parts show that "Since last unplugged" time spent without sleeping is 10m 33s (99.9998%), and time spent with screen on is 3m 23s.
im thinking of buying this phone is it available in India ? also can this device be rooted n what about the custom roms ? are they available as there is nthng on XDA :'( . And what about its battery life even being 1500mah is it so awful ?

Now after factory reset it seems that this is fixed. Over night with Wi-Fi and all sync's enabled, it took about 20% which is quite ok.

The problem is back... For some unknown reason the phone doesn't go to sleep and starts to use more battery.
Battery History:
Other usage, since last unplugged:
Running (100%)
Screen on (3,2%)
Partial wake usage, since last unplugged:
Android System: Total time: 13s
Dialer: Total time: 0s
Maps: Total time: 0s
It seems that reboot helps with this every time. After reboot, running-% is 32.9 when screen on is 6.5%. It would still be interesting and helpful to know what causes this.
its an android thing

Do you mean it's a common bug, or is it normal thing for Android to not go to sleep after few hours of using the phone?

That's not true. My battery history shows that correct(as far as I can perceive) running time.

I get most of the time also. But after charging, at one point (after some time) for some reason the time spent without sleeping goes to 99%. The problem is, that the partial wake usage doesn't show that something is wrong. Usually restart helps, but sometimes it can be already late, because 100% running has already taken quite much of the battery.
Also, when the time spent without sleeping is 99% or 100%, the CPU is still NOT in heavy use. So something just prevents the phone to go to sleep mode, and it seems that it is not the CPU that causes it.

I got it through the phone, it was the 2.2.1 B136SP02 update. Not online at Huawei website. It doesn't seem to have improved battery life alas (or the frequent WiFi dropouts I've had since new, particularly while downloading app updates). Main feature of the update is WiFi tethering/hotspot support, at last...
What seems to have worked for me after a couple of weeks++ of REALLY crappy battery life is a battery stats wipe.
FullCharge while the phone was off. First boot in recovery, battery wipe and then i just let it run close to dry before the first charge (almost 48 hours of medium use). Note here that i am now using the charger that came with the phone because i noticed that my generic usb one had an output of 0.7A instead of the full 1A of the factory charger.
Another point arose however. Does anyone else have stability issues when battery drops below 25%? I am talking about some serious crash/reboot/lag/noradio issues.
So I noticed something weird about my phone. When you go to menu>settings>about phone>battery usage, it tells you when you last unplugged well my phone does not seem to reset that timer always . I can plug it in for a couple hours and take it off charge (battery level does increase) and it will still say i have been unplugged for X amount of hours. Anyone have this issue. Never happened in any of my previous android phones. Btw stock Nexus S 4g, Im truly stumped on this and looks like no one else has this issue.
I think it only resets once the battery becomes fully charged.
Thats what it seems like its doing but i know my previous android devices would restart the timer when i would plug in even for a second or when i turn off my phone and turn it back on granted my last phone was a Epic on 2.2 so i don't know if that makes a difference. This one only seems to do it at a full charge like you said hmm interesting. Other people having the same results?
I've seen it before. I once had it going to five days. I tried restarting the phone, but didn't work. Had to clear battery stats in recovery but like you said you're stock.
yes, since gingerbread, battery stats reset only if you keep charging until 90% or more. I have a nexus one and with 2.2 it reset every time, but not anymore.
Okay good to know its just a gingerbread 90% thing because i thought something was messed up. thanks!
Did you used the USB-charger? Then it won't reset the timer.
Sent from my Nexus S using XDA App
Yes I am using the Stock charger in my PC or plugged into the wall plug it wont reset it until it hits a high battery charge level.
Soo i fully charged to 95% last night and when i took it off this morning the timer still didn't reset hmmm at this point im tempted to go around root and clear my battery stats
No one has mentioned the battery usage graph (hard to notice, but there behind the "Time since last charge" message on the top) which shows battery usage over time since last full charge, including interim partial charges as hills...

I am now getting this problem too where it doesn't reset, even after it charges overnight and hits a high charge amount (94+%). Did you ever figure out a way to get it to reset to 0 sec on battery without resetting battery stats?

Android phone battery-saving tips

Good post thanks.
Got 1 tip Ive noticed recently and that is to ''Reboot your phone at very least once a week''. Reason for this as Ive left it for 2 weeks with out reboot and charged up full and went to work which was 40 mins away. Then noticed that battery was at 80%. So an hour later was down to 50%. I checked my running services and nothing running only standard android stuff. So I rebooted and then was on 40% and that lasted me 11hrs of radio while at work with 4 calls I made.
I know you can ''wipe battery stats'' in Recovery but I didn't use it this time but rebooting the phone stopped the massive drain.
May be different for you?
I wiped the battery stats when it was fully charged, and now it lasts 2 days without recharge. I'm also running juice defender for some more power saving.
I've got the 16gb nexus 7 (non 3g).
I've had it for less then a year and the battery life had been great. But starting over the last few days the battery is horrible. After a full charge over night my battery was down to 50% today. And that's with hardly any use. I used it for maybe an hour total and at least half of that time was just reading reddit.
I haven't changed any settings recently. This is all stock, no mods, not even rooted.
The battery usage right new says it's been 13 hours, and it's down to 48% and Android os accounts for 27% Followed by screen at 18% and WiFi at 9%. Those are the top 3 showing for battery usage.
Any suggestions as to what's going wrong it how to diagnose be fix it?
Thanks
Either your battery is bad or you have a stray process running somewhere.You might want to factory reset it, possibly even reflash your image.

Would the battery go bad that fast though? In my experience batteries usually gradually get worse. This went from losing a few percent of power to losing half power in the span of a day.
I might try the factory reset - just have to make sure everything is backed up. This tablet isn't rooted so i dont have titanium backup on it.

Doubtful it's the battery... my money is on a rogue app!!!
Hi, merkk...
It's possible, that as the previous poster suggests, some rogue app is 'eating' your battery.
The biggest consumer of power is the screen, so ensure you haven't got it set it maximum brightness... and ensure auto-brightness is enabled in settings.
Another thing you can check, is your WiFi setting... on my Nexus 7, I have 'Keep WiFi on during Sleep' set to 'Never'... it's not a setting that is easily found - it's buried in SETTINGS>>Wi-Fi>>overflow MENU (three dots, top right hand corner)>>ADVANCED>>Keep WiFi on during Sleep.
It also might be worth checking if the SYNCING of your respective accounts (Google, Twitter, etc.), haven't been inadvertently changed. Particularly the SYNCING of your Google account... which by default, SYNCs a lot of stuff and frequently. This will keep WiFi awake, and may cause battery drain. Go to SETTINGS>>ACCOUNTS>>GOOGLE and disable what you don't need to be SYNCed.
-----------------------------------------------------------------------------
It's unfortunate that your Nexus 7 isn't rooted, because there are a couple of excellent diagnostic apps available (GSam Battery Monitor and BetterBatteryStats) which provide more granular and finely detailed battery info/history than the standard Android battery info screen... and are useful for tracking down problematic apps that might be keeping the device unnecessarily awake ('wakelocks', etc.).
However, due to changes in Android 4.4 (KitKat), these apps now require root access to read and report battery stats info.
If your Nexus 7 is running any version of Android BEFORE 4.4 KitKat (and some haven't updated yet), then you don't need root to run these diagnostic apps.
-----------------------------------------------------------------------------
It's sometimes the case, with Android, that there will be occasional peculiarities with battery performance... and in my experience, it's almost always the case, it's due to something the user did... some app or widget installed. I'm currently experiencing similar battery issues on my Samsung Galaxy S3, but having run GSam for a couple of days, I think I have the culprit identified. If I can't eliminate the problem, I'll uninstall the app.
-----------------------------------------------------------------------------
Hope my ruminations are of some use.
Rgrds,
Ged.
Gedblake, thanks for the suggestions. For whatever reason, today it seems to be back to normal. The only thing i did last night was drain the batter to around 10%, turn it off, and let it charge while turned off.
Turned it back on today,used it for about 15 minutes or so playing a game. And now just about 5 hours after turning it on, it's down to 92% which is what I'd normally expect.
I'll try some of your suggestions if the problem re-occurs.
I noticed that my N7 (2012) has been draining quite a bit lately. Watching the battery stats, it seems Google Wallet was eating up some major battery. It was 2nd at 29% with the screen number 1 at 38%.
Not sure what the heck Google Wallet was doing, but I killed it and things seem to have stabilized.
battery drain after update?
For years I've had the same routine. I use my Nexus 7 all day for work, mostly notes. In between I play, (youtube, E-reader, etc). Every night I plug it in to charge and in the morning it's fully charged and ready to go. On Tues, I received the OTA update for 4.4.4 I noticed this morning that after a full night's charge, the battery only reports 50% charge. Is this the beginning of the end? What steps should I take from here? I recently bricked by GS3 so I depend on this thing now more then ever, any help would be sooooo appreciated.

I'd just restart it and let it charge again. I've updated mine a while ago and haven't had any issues.

I'm on a custom 4.4.2 ROM and I have had intermittent draining behavior as well.
Sync is off, location services off, I turn off wifi manually, and I always clear recents before I have my tablet sleep. I have greenify installed. I'm using better battery stats.
My issue seems to be similar, but I am also having battery percentages jump around.
Earlier today it went from 26% to 43% in the middle of me using it. Without charging. It frequently does this, both lesser and greater values reported. I've had my tablet shut down in the 30% range. I've had it shut itself off on 4%. I've had it drain all the way to 0% and then some before shutting down. I've had it turn itself off and when I power it back on the tablet is thinking it is at 25% or more.
I haven't been getting much more than an hour of screen time with my tablet lately. Clean fresh install of my ROM.
But I've never, until the last couple of days, had it go from a small percent to a large percent active during use. I took screenshots. I even started a thread to talk about it but nobody has responded yet.
Has anyone else ran into this behavior? Is it a sign of a soon to be dead battery?
mine got almost 30% drained on idle, airplane mode, screen off for 3 hours (tested on stock rom 4.4.3. GApps + Swiftkey + BBM + Facebook only)
my nexus 7 never lasted a day, only half a day max.
trying GSam app, hope it helps in knowing what's eating up batteries.
