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.

PoisonWolf mate these techniques used to work on old battery but the new lithium batteries don't need these manual calibration process...

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 hd2 is losing almost 10 % per hour. If i use wifi to update weather etc in sence it may lose 5% in under 5 minutes~!!
I am sure that is coming from a bad app i am using, causing battery drain!!
Please help, any ideas which it may be??
I have installed both free apps and apps i had bought for my hd as well.

Thats all!! All installed into main memory..(and of course most of them not active as task never! - only apps that running like taskbar, task manager, resco etc..)
ANY IDEAS WHAT TO TRY??
What I would do in your situation it would be to do a hard-reset and check if the situation keeps the same. If not, I would start to install apps one by one and check which one is doing that.
If i cant find any other solution, yes ill do that. But i want to go the other way round, and simply by unistalling find the problem.
The truth is though that the first 24 hours that i had my hd as stock (no apps, not even my contacts) and only the sence configured the battery was still draining fast..And with little usage i lost 40% in about 5 hours..Still far away from the battery tests from our friend xmoo here in xda..
Other users experience???? Please post here so we can check!
I too am experiencing fast battery drain. Only used for about1 hour and already 77% left.
I am wondering.... if anyone who is experiencing fast drain did not charge their phone for a good few hours upon receipt or if it was used while charging for first time.
in the modaco hands-on review, Paul said his battery improved after a few depletion/charging cycles
Hi all ! How should we do it corectly? Is there a plan? 3 charges of 12 h after complete discharge or something like that?
Thank you in advance !
i don't have the answer but can confirm great battery life. I plugged mine in immediately when i got it and left it plugged i over night. To my surprise, i am getting the best battery live of any htc product ive owned (and that's a lot lol) with pretty substantial use. Now the difference between you and me may be 3g. I live in the states and don't get 3g, also i set mine to gsm only. Maybe try gsm only for a few hours?
I've also turned off auto brightness and have it on the lowest setting most of the time, as it's enough for me and helps get the most out of the battery.
the correct way to get the battery in best possible shape
before first use...charge over night
..then use untill battery is completely empty...
...then load over night again (that means about 10 hours)
you do that 10 times in a raw and your battery will be in the best possible shape. From there, you don't have to do the extremes every time but at the beginning it takes about 10 full charging circles for the battery to use its full potential.

thats complete bull**** on litium ion batteries.
Li-ion doesn't need to do the full charging cicles and deplete the 100% of the battery will damage the battery.
My experience with the HD2 battery is great: I get two to three days with one chargecycle. I have set the networktype on GSM and not on Auto.. I think this helps.

this is the only way I can ever get my handsets to go more than one day! Fine for emails / calendar sync, not so handy for browsing/maps though!
What I do with my mobiles is:
When I open it, I use it till the battery is completly over;
Charge the mobile during 10/12 h;
Then use the mobile normally and charge it whenever I want;
After 1 month, I let the battery get completly drained and then do another full charge.
Altough is LI-ON battery and it has no memory, it's necessary to do a "full" recharge from time to time to "calibrate". Don't know if it's really like that, but it's what I've been doing and it works great for me.
I HAVE 3G ENABLED ALL THE TIME,AND WHEN I GOT THE PHONE I BEGAN USING IT ASAP WITG THE CHARGER ON, TILL 100 percent! Writing from thd phone noe as it... charges!51 percent with almost no usage the last 7 hours! Maybe i ll try the full drain thing! Just to check!
ps. also the typing expirience sucks for me.does the aling screen option works in this kind of screen!?
How's the reception in your area? I had a phone that during night, with only GSM network, drained 30% in my home. But in other areas, 1/2% only.

1) let it charge overnight (8hr+), phone off, straight from socket not through pc usb
2) fully drain the battery then fully recharge. repeat for 2-3 times
3) try flight mode (if there is one), let it idle for 1 hour or more. any drain?
4) go through settings and switch off periodic updates (activesync, weather, email). any drain?
5) remove questionable program(s) and see if it helps
6) worst case scenario, hard reset and check if battery usage is back to normal. then install one program at a time

that's the best way to destroy battery. it is a li-ion: first time it's importante to have fast charge.
wot i do is:
-fast charge and never let the battery die.
in this way, alla my phone have an eccellent battery as the first day.
There must be something corrupted with your device.
I had min in use from Friday noon to Sunday late afternoon (forgot my charger at home):
about 1 hour of phone usage, push mail activated, weather sync (syncs all hours), took 5 pictures (2 footprint and 3 normal in hires) and alarm at Saturday and Sunday morning
battery dropped from 100% to 21% in this timeframe with the above usage. I think this is not too bad

probably you aren't very knowledgable regarding batteries...I am.
altho Lithium-Ion batteries have no memory, they still need to be charged correctly at the beginning to free up the potential.
but whatever...do whatever makes you sleep at night
Can you tell us exactly what is the best charging routine for our phone please. When new and when its been used for a while. Thanks.
Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?
Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.
Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??
Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...
Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.
P_
this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.
Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........
Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?
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.

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?

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.
Hello guys
I have my galaxy s4 i9505 android 4.4.2 . Is that normal, that my phones battery discharges in 2 h 30 min average (from 100%), when i play heavy games like asphalt 8 from fully charged battery till its discharge with wifi on and on 50 % brightness? Also when im surf the net, stay on fb and do stuff like that, my phones battery discharges in 4 hours. I say thats not normal. And by the now my phones battery discharges 1% in 2-1min
So its that a foulty battery problem, charging port problem or else? Dont tell me reset my phone cus, i done that 10 times already and it didint help
Im pretty sure its not Running apps problem either, cus my phone dont heat.

Let's be organized:
1. Faulty charging port: can be, if you phone charges too long. nothing related with discharge speed
2. Faulty battery: check battery SN, if it starts with BD letters, can be. In this case, the battery would be visually swollen, and your phone shall randomly reset with charge from 80 to 30%, and shall not be able to start without the charger connected.
3. Discharge of 60% per hour is possible, depends from the apps running in background. Install Battery Monitor Widget or something similar to investigate closer.

Thanks for reply I forgot to mention that my charging port is weird, sometimes charges phone, sometimes not. Recently my phone charges only when its turned of completely, when phone is on with charger connected its discharges. Also i can say that thats not a charger problem, because my brothers S3 charges very well with it. I'm i have ordered the new charging cable/part for my phone, and hopping to fix charging issues.
Another problem is that my phone in powering On process goes to Download mode without key combination and dont boot up (sometimes), also in the same way rondomly when i press power on button it goes to recovery mode (without key combination). Is that problem may be realated to this one i stated before (about charging).
It's perfectly normal. There is nothing wrong with your phone.

Really? 2.5h is good on gaiming and wi-fi with 50% brightness? When browsing the net, my phone discharges in rate like 1%/3mins... (average)
it depends entirely on usage. 2.5 hours screen time while gaming is pretty good I think. on stock rom i can manage anything between 1.5 and 4 hours screen time, but it also depends on usage during screen time. if you're running something that's quite hard work on the cpu/gpu and with the srceen constantly on....like gaming.....then obviously that will drain your battery faster than just browsing the web or texting etc.
generally speaking s4 will last through a days normal use quite easily.....but then it depends on how you define normal days use.

Thanks for reply So its nothing to worry about? I had S3 and it lasted much longer than my current S4. Of course i need to look at its 5'' display and 1080p resolution If you guys getting same battery life while heavily using your phones, it means it's ok and i don't have consider of changing battery ?
yeah i think from the sounds of your usage, that's about right for a stock rom.
if you are still only getting about 2-4 hours total use (i.e. battery dead from 100% down to 0%) from your normal daily use while you're at work/school or whatever (i.e. where it's sat idle for most of the day), then you've probably got something wrong. but given that you said you were playing games etc contantly and still got 2.5 hours screen time, that's ok i think.
you can always try and squeeze some more out using custom kernels etc, but if you are not certain it's some other fault i#d try and see what battery life you get on idle first so that you don't lose warranty by flashing a custom system. so yeah try for a day or two leaving it with just normal usage or idle whenever possible to compare

THAT is NOT normal... and yes, it may be somehow related... if your phone shows that often, and if it is under warranty, I'd consider going to service center
ooops, yeah i totally missed the post about your download mode issue and faulty charging port. if you're in warranty, take it back.
