[Q] Terrible Battery Life - Hardware Fault?

I've had my new desire z about 2 weeks now, and am utterly dissapointed by a frankly dreadful battery life.
It's my second DZ, given the original was nicked, but (kicks self) wasn't insured, so was purchased from a supplier that shipped my phone from Hong Kong (I live in UK, and the new phone is an identical model, except for a slight difference in key layout - A2727 I think is model number)
The original phone would give me over two days life with very low use, which i considered to be fair for a decent smart phone.
The new phone barely gives me 10 hours with no use. I've done a couple of tests - unplugged it at 2am, but 8am it's at 30% or lower. This was done with all data connections turned off.
If i leave the new phone to go dead then that's it - it won't charge. The only way i've found to get juice back into the battery is to hold it in my old touch-pro 2 until it's charged enough to charge from the desire.
Last night was the clincher. I've gone out with some friends to the pub. I had a conversation over it, and checked my battery life - 42%. As a last dith effort i factory reset the phone at that point to rule out a mischevious app, and checked - 39%
Within 2 hours, and with no use at all that was down at 8%. In order to avoid the charge issue i cut my losses and turned it off at that point. Once home (oh, about 4 hours later maybe) I was unable to turn it back on. I then left it plugged in overnight, and was still unable to turn it on this morning until i'd done my cross-phone charging trick.
I'm now entirely convinced there's some form of hardware issue at fault here, so i'm wondering if anyone else has had the same problem with this phone before? I see lots of thread regarding poor battery life, but most seem to be solved by turning data off or some rouge app, neither of which are an issue in this case. Also, any hints for making my life easier when I phone HTC tomorrow? I've read elsewhere their support might not be all it should be.
Thanks in advance for any help! I've ready to pull my hair out as what is a fantastic phone otherwise has been completely ruined by this battery issue.

I think you should get a new battery to rule out that the battery itself isn't a problem. I had similar issues with my G1 a while back and it solved a lot of wierd, seemingly unrelated problems. Batteries are pretty cheap online, $15 or so and some are free shipping.
The way that I figured out my battery was toast was by comparing it to other batteries. it had a bulge in the center where it should have been flat. Fingers crossed it isn't hardware.

had already tried a diff battery (did you know you can chew a corner off a touch pro 2 battery and make it fit??) Which i know worked fine in the old nicked dz and imo as i was getting same issue ruled out battery problem.
anyway... phone has now been returned and i'm waiting 2-3 weeks to get it repaired under warranty (though am hoping for complete replacement obviously)

Chewing on batteries has got to get you extra xda brownie points. I'll remember that

I'd like to think there was some techincal or engineering skill in there somewhere.
but it was mostly "Well, apart form this nugget of plastic they're the same shape..."

I'm having the exact same problem... When you take you shutdown to recharge a dead battery, does it sometimes try to turn back on? I left my apartment like 30m ago with 100% battery, and I'm at 84% and declining. There's nothing running. And I've replaced the battery, same issue.
I think I might just RMA this one.. seems like an engineering issues.
Edit: I'm the 40 seconds it took me to type this, battery dropped to 82%.

Wanted to bump this post. I've since wiped / reloaded and wiped battery stats. It's still jacked. I think it's an internal electrical thing. Reason is: I'll power down to take the battery out. When I put the other one in, it'll turn back on. Or if I power down to charge, it'll turn back on - plugged in or not. I don't want to deal with the RMA process again, but I think it's my only choice. I've taken two phone calls this AM @ 100%, and it's at 96% now. Drives me insane. Ugh... I'll call TMO. Anyone know if the replacements are still rootable?

So... I had my phone replaced, and it's still doing the horrid battery thing. Flashed CM 7.1 RC3 or w/e the latest is, cycled one battery - and it drops like a stone. I have two chargers (one at work, one at home) and they both charge the phone up to 100%. But it's still losing battery life quicker than I'd like. I used to be able to get a good 18 hours out of this phone. Even with a new battery and a new phone, it's acting up. I'll try to flash an older ROM and see if it's the same thing. I updated to #130 nightly from 7/10. We'll see how it lasts today. But I do remember I had horrible luck with CM's ROM's on my G1. Battery would just drain for no reason. The main process taking up the most battery life is "Cell standby" so I changed to the latest radio - and it still drops. OP - have you figured out your problem? I've removed a ton of apps, and it's still messing up. I listen to music for... 45m in the AM, and I get down to 54%. I've formatted my SD Card as well.. it's driving me insane.

I just flashed CM 7.1 a few days ago and while the ROM is great, it does seem to be a litter harder on my battery than 6.1 was. With light/moderate usage yesterday, I got about 16 hours and that was running the battery almost completely dead. With heavy usage, I get about 10 hours and need a bump charge in the afternoon.
You might want to look into getting a Mugen 1800mah battery. You can get them on Ebay from 35-40 dollars. The seller 'nakedcellphone' is based out of Southern California and another user has confirmed ordering from them and getting a legitimate battery (lots of fakes on Ebay). Either that, or carry a charger with you...
Have you tried using Watchdog to see if there are any 'rogue' apps that are causing the drain by running in the background? What about going to spare parts > battery history > Partial Wake usage? There it will show apps that are draining your battery when you're not 'actively' using your phone. For me, the Android System is the highest drain in that menu. Good luck! Hope some of this helps!

I just checked spare parts, and there's nothing too odd in there. Just my music app. And I've changed that too - thought Winamp was killing me. I'll check Watchdog. This is a brand new OEM battery along with an RMA'd G2. It has to be the OS / Radio or something. I've stripped like every non-essential app too.

I am so sick of this tablet...

Had to return the first one as the battery dropped so quickly I could see it - dropped by about 5% at a time every 2 minutes or so...
The one I've got now has been working fine (for the last 2 weeks) until today.
Turned the screen off at about 65% battery. Turned it on about 3 hours later and it had dropped to 43% without the screen being used. Mediaserver and Google Services had been using most of it apparently.
Rebooted it. It then went from 43% to 36% to 26% to 22% to 15% to 9% to 2% in about 5 minutes.
How can Samsung release something so useless?? Is it the software??

Wow that's f-ed up sorry about your luck.
htc one

No luck man.
I'm very happy with mine...

Hi. No, not rooted.
The battery stayed at 2% for ages. I then turned it off and on again, and the battery showed as 36% again. It then dropped straight to 23% which is where it is now.
Seems all over the place...

you try a factory reset? worked for my battery drain problem :good:

Not with this one, but I did with the previous one, several times.
It's not acceptable to me to have to wipe my tablet routinely to get it to work properly...
How long has it been since you did the reset?
Thanks

Have you factory reset and not installed any programs to monitor usage?
Perhaps something your installing is doing it. Are you using a microsd card?
I just starting charging my tablet after 1 day and 17 hours with 9 hours and 30 minutes of screen on time.
And I still had 18% battery left. I'm not saying it to brag just that battery life is fine on this tablet.
Until then please search Google for mediaserver battery drain. This is not running on my tablet btw.

Media server can happen if you have some corrupt media file the tablet is trying to read and identify over and over again

Threads like this are always interesting. If every owner on this forum's N10.1-14 performed like OP's don't you'd think it would be on the front page? So OP's issue is something unique. It could be:
A manufacturing issue that affected a batch of N10.1-14's. If OP's exchanging at the same place all their devices could be from the same batch.
Samsung uses different s/w in different regions and perhaps there's a battery draining s/w issue in the particular ROM OP's using. But unless OP's from Antartica you'd think others from his region would be reporting the same issue.
OP's loaded something on his device that's either incompatible with 4.3 or Exynos 5420. A lot of older legacy apps still run on newer Android devices but don't run well and create issues. If OP's using restore his old apps are being installed as soon as he signs in to his Google and/or Samsung account.
Of the three I'm guessng number 3 is the most likely. I have a SM-601 with 130 apps installed, a dozen syncs running, and two Exchange push account always downloading. Used exactly the way I used my N-8000 I'm getting about 10% less battery life. That seems about right to me considering the PPI is doubled, the SoC is more powerful, and I'm using also Samsung's motion, voice, and air sensors which didn't exist on the N-8000.
OP, try setting up the tablet without signing in to either your Google or Samsung account. That'll make sure no apps are installed without your knowledge. See if the battery drain is still there. If it's not, your issue is s/w and not the s/w pre-installed by Samsung. Good luck.

Thanks for the replies.
It seems there are 2 separate issues.
1. The mediaserver battery drain (I do have a micro sd card, but haven't recently added loads of new files or anything). The tablet has run fine for 2 weeks without this issue, and I haven't recently installed any new apps.
2. The fact that the tablet doesn't know how much charge it has - goes from 2% back up to 36% without being charged etc.
I'm not sure what to do. I noticed that google play music was running in task manager so ive disabled that, and have fully run down and am fully recharging the battery. When in plugged the charger in symbol went from showing battery empty to about 20% charged instantly which doesn't bode well...
If I still have an issue i guess I will exchange it a 2nd time for a 3rd unit...
Thanks for the help

Thanks for that mate. I'd already seen that thread but thanks anyway.
Before this issue today I was happy with the battery life. My problem is not a general battery life issue - something is obviously seriously wrong with my unit...

I reset it once, a few weeks ago and its been solid with power usage since.

Perhaps it is being effective by the new Google Play Services, which appears to have a battery draining issue. This started in the last week, I believe.

The battery drain just happen recently, isn't it? I've just bought my Note for 4 days, on the first and second day, the battery is awesome, but from the third day it run down from 45% to 5% in minutes.... I think that related to some update service and happen to massive device recently!

Well, it is a possibility. My first gen Note 10.1 wifi does not seem effected by it. It is on 4.1.2. I also do not think this effects all devices. Wondering if it is a 4.2.2 and up issue or something along those lines. I only suggest it a possibility to check into.

http://forum.xda-developers.com/showthread.php?t=2378962
in here state that the problem could come from the new update of Google Play Store. I did remember that it is updated before the problem appeared (but not so sure). Just remove the update of Play store and see the result. Will report back

Just to update you all in case other people are having the same issue - I disabled google play music, ran thrbattery right down so the tablet switched off, charged back up to 100% and then used it normally. Battery seems much better. Although it did drain really quickly from about 35% to about 5%, but over an hour or so, not in minutes like before.
Weird apps have stopped using all the battery - its now used by about 90% screen, 5% android os etc which seems normal.
Still, there is always the worry that ill get it of its case one day when I nred need to use it and the battery will be flat!

P600 wifi getting 14 hour battery life here. Been using it all day and played some games too. Im happy with the battery life.
If people get together and help make knox proof root, I might be interested in making a rom with all my battery saving goodness in. Or work with some people to make a nice clean, lean rom. Who knows.

Battery percentage keeps changing?

This Amazon Fire phone has been around almost 5 years, and its just started to get buggy on me. The battery will keep switching from whatever I have currently to 50%, so something like going from 78% to 50% or from 32% to 50%. In addition to this, my phone won't charge. It keeps switching to charged and not charged.
Not only is it this, but at the same time i've been getting "Invalid SIM" in place. I'd have to restart it once or twice to get my data back and all, and it would happen frequently. All of this started about two or three days ago, and now I can't turn on my phone because it's not charged but also displays 50%.
Any advice on what to do? Is this the death of my phone? I'd be more descriptive but I'm not too familiar with anything around here nor am I very educated with phones, I've just been told to post here in hopes for help.

Must be because you have a VERY early prototype considering it didn't announce to the rest of the world until July 2014.
Seriously though, batteries die. If you've been a heavy user for 3 years, it's time to hold a wake and then move on.

I replaced the battery in January and its been holding up, but you're right. Looks like I better start looking for a new phone haha.

For all the phones I have owned over the years, this usually happens if the battery is going bad. You say you replaced battery in January, so, I am guessing the replacement battery was not original but rather a cheap made in China oem replacement because an original battery for this phone is suppose to give you around 750 charge cycles.
Install the app called 'Charge Cycle Battery Stats' from Google Play, which among other things, will show you how many cycles your battery have on it currently. Other than that, I would suggest buy another battery, or buy one of the defective Amazon fire phones on eBay (sometimes a phone with broken screen goes for almost same price as you would find a cheap, not original battery for) for parts, take out the battery from it and use that. At least this way you will be putting an original battery in your phone. Besides, while this phone was really good, it is pretty old by today's standards and on its way out especially due to outdated software, and it may not be worth spending more than $25 to fix it.

The battery that Amazon chose was made by a third party for them and it's different from other devices - it has a chip on it that literally reports the full capacity of the battery (from what I've been able to tell) to the battery charging circuit in the phone itself. When it reaches a point of about 30% - again from what I've been able to gather based on reports - meaning the lifespan capacity of the battery aka 30% of the full original charging capacity and not the daily "per charge" run time the battery charging circuit literally just shuts off the phone even though there's actually enough charge on the device to make it work even for short periods of time.
It's a pretty lame thing to do, it's basically killing the use of the phone even in spite of it being perfectly functional but with the reduced overall capacity to stay running for long periods of time. It's crappy business really but since Amazon didn't care then and doesn't care now it doesn't matter at all to 'em but to those of us that own Fire Phones (as I now do) I still say it's a pretty shoddy thing to force upon unsuspecting owners.
Anyway, once it gets to that point the battery charging circuit will shut the phone off and that's what the Amazon logo bootloop is caused by from my research. As noted above in another post, Li-Ion and even Li-Po batteries are generally considered to have overall lifespans of roughly 18 to 24 months based on people charging them at least once per day (it's not a perfect science since people plug in at various times). If you've had that Fire Phone since it came out that was literally 3 years ago (June 2014) and sold through AT&T stores in July 2014.
So, I don't know where that 5 year thing came from but it's not technically even 3 years old - that happens near the end of June so another 2 weeks to go. I know some folks are bad with dates and periods of time but there's a rather huge difference between 3 years and 5.

Fire phone battery indication
My Dad have been using this phone for a year and a half. The battery indicator doesn't move, it sticks to 100 percent and stays the whole day and suddenly it dies. Basically the battery indicator is not working, any ideas?

SM T-700 is loosing energy while turned off!!!

Hi all and Happy New Year.
The problem is that while my T-700 is turned off (not screen off) and having installed a new battery (doing all the preparations needed, like reset to factory settings, clear cache, recalibrate new battery), in two days time the battery from 100% is COMPLETELY DRAINED like a freaking 0%! And allow me to repeat ...WHILE TURNED OFF!!!
The battery is brand new, and the tablet is "untouched" (meaning unrooted, no UB, Knox is 0 and I have installed only the Official OTA's provided by Samsung).
WTF???
I've contacted the place where I bought the battery and they told me that they will send me a new one, BUT that was the exact same reason why I bought this one and changed my battery in the first place (of course I haven't told them that) lol.
Could this be a hardware issue, or was I so unlucky that I just happend to buy a "dead" battery?
Any ideas? Plz help, I'm in desperate need of my T-700 for working purposes...
Thanx in advance!

ANYONE??????

I can't say my battery is brand new, but i have been having battery issues lately no matter what rom I use or if I return back to stock. I have no idea why it would be doing so though.

Do you think we can blame the tablet's motherboard? Cause it's the last thing I can think of that would be responsible for these issues since software obviously isn't (At least in my case I hope for a DOA battery issue fingers crossed..).
Anyway, I've ordered another battery (e-bay) that would be arriving in approx 3 weeks. We'll see...
If no luck again, then a repair center will provide the appropriate answers...

I have the same issue with my Tab S SM-T700 and I have tried flashing many different ROMs, the problem still exists. I would suspect a hardware fault, either the battery management IC or some other consumer that doesn't power down properly. Don't think this can be fixed without a new motherboard, at least it's still usable plugged in!

I have purchased several batteries for my SM-T700 from different suppliers on eBay. Apparently, there is a big market for batteries pulled from old devices and relabeled as "new". Based on the poor specifications (I.e. battery capacity, battery life) I suspect that not one of them was actually new. For example, one battery held so little charge after just 16 discharge/recharge cycles that I had to replace it. Perhaps, you have a bad battery.

There is an option somewhere in the settings to turn off wifi when the tablet is not in use. This solved this problem for me. It's the misbehaving apps that "call home" or use other resources while your tablet is supposedly asleep. While it's possible to hunt down at least some of these apps, it's kind of hopeless because some of the worst offenders are google's own apps and services. When wifi is not available they all go to sleep and the tablet can now stay idle with screen off for days without draining battery. Before I enabled this option, the tablet would literally drain 1 percent of charge per hour even though not used, so after two days of no use 50% was gone.

True... But previously bought battery was not from ebay but from a retail seller... The newly bought one will be from eBay. I'm still waiting on that. Will inform when it will arrive...

That was it... Main board problem... Need to spend 200€ (which of course I won't) in order to fix it. Still, I can work with it as long as it is always plugged in... Unfortunately it was not a battery issue...

Sudden battery drop

Good morning all. I have owned this device for a few weeks now and am enjoying it immensely. I bought it second hand from swappa. The warranty/ownership was transferred to my name.
Twice in the past few days I have had significant battery drain. The level indicated 60% when I started running. I watch Netflix or the like for 45 minutes or so then I get the battery saver notification telling me I am down to about 5%. It makes me worried that this happened more than once.
I am wondering, should I suspect faulty hardware/battery? And if so, should I rma? I attempted to clean flash October factory images with no improvement.
Thanks and have a nice day.

I would install Accubattery and let the phone go through a few full charging sessions. Try to start charging above 20%. Don't take the phone off the charger until the APP tells you the phone is full. You will notice the phone continues to charge even after the PHONE says it is 100%. Once you have done this a few times you will see your battery's estimated remaining capacity as compared with a new battery under the Health tab. It will show you both the mAh and percentage. This will rule out the battery. If the battery is good (eg. >90%) then try a factory reset. Might as well wait a few days until we get the November security update on the 5th. Good luck.

I have faced the same issue since 3-4 days...the battery is draining a lot faster.
