Official HTC Froyo battery life?

Greetings...
I've been hesitating about upgrading to official HTC 2.2 based ROMs mainly because of concerns over battery life. I have great battery life (4d+ standby, medium use) with Sparta ROM (no Sense) and would like get the same with Froyo.
According to your experience is that possible? What's your battery life like? Thanks in advance for sharing...

Both of NeYoPhyTe's ROM's have a very good battery life i believe, I'm currently using ۵.NeoPhyTe Mod v1.7.1 Sense-FroYo 2.2 · ROM and I'm just charging to 100% and i will give it a try.
I think that there should be a "preserve battery life" thread with people offering their tips on how best to preserve battery life to full extent, i have the usual not syncing facebook twitter an all that, my brightness is at 33% at all times (except if I'm outside) but im sure that there is more that i could be doing to save a little extra......

took off the charger this morning around 7u30, wifi on + gps on (accidentaly though) until 9u. Now 12u15, and still got 93%. Only got 1 and sent 1 message so far.
not bad i think and i'm using MCR r7 wip.

Im sorry but i dont get it... you have the very best gadget on the market right now and you use it for 4 days of standby and low medium use? Why did u buy this phone?
If u arent using ur phone, dont go to froyo because battery life will decrease due to so many improvements and better wifi signal that burns a lot more battery.
I got roufianosV6 and i use my phone very heavily, fb sync, gmail, lots of sms and calls, internet all the time, wifi on 24/7, using various apps,... and i get 15-20% battery left at the end of the day and im very pleased with my battery life.
If u get 4+ days that means practically no usage and it meabs u dont even need this phone.. since u do have it, i would really disadvice u to go on 2.2, because u would go only for the number not for actually using the goodies.
Besides... you guys live in woods without electricity or u have to pay for each charging of the phone?

What?
I know plenty of people who would need long battery life over raping their phone for all its worth over 15h. Whenever I go on holiday for example, I don't want the battery cutting off mid flight because im playing music through last.fm. Or if I'm on the train, I wan't to know that I can make calls the next day.

he is right though in a way, why have a high end, top performing device, if your not going to use it for 4 days? I see what you are saying, about wanting to be able to use it without having to re-charge every 5 hours or so, and the only solution would be to buy a spare battery for those long haul trips. I would be happy getting 24 hours with moderate to heavy use.

Just wanted to write that - buy a spare battery for planed trips with no electricity on the way. Desire holds a day and a half of medium usage - only for what u need and when u need - calls and sms with no wifi or gps or syncing weather fb music radio etc..
Or... buy a sonyericsson walkman edition, i guarantee u better sound and longer battery life. Lasts a week of medium use on my SE w810.
U can buy double sized batteries i think for the desire as well but it looks ugly from the back. Besides, desire has micro and normal usb cable, and you can charge it just about anywhere. Moreover microusb will be official charger for europe and from soon to come on, all the mobile manufacturers will gave to make micro usb chargers and u will be able to fill up your phone from ur friends charger.
Desire has a top battery comparing to the processes it runs all the time and to the great amoled. I have it ob full brightness all the time. I dont get ppl reducing the amoled brightness as its the fabulous colors that make the screen so insanely great. Its like buying a porshe and installing a golf V 1.2 disel engine because porshe uses to much fuel...
Im sorry but there must be something sacrafised to have such a high end device and that is battery in this case. I really cant imagine using the desire with all inclusive apps use. It lasts a day and thats mire than enough for me - use it over day, recharge over night. If some ppl have desire for bragging that they own a best device out there but they dont use it... well then theres the battery problem indeed. (im not implying to anyone here, its meant in general)

On stock 2.1 ROM my desire lives only 1 day with 2G only, BT off, Wi-Fi on, no fb and no gtalk, some IM (jabber via Jabiru). In general, my phone wasn't overloaded.
When had upgraded to froyo (AdamG's SenseFroyo 1.0c) i got 2 days uptime with same using conditions. And additionally i can watch one movie or surf web for ~2 hours

Extra batteries suck because you need to restart the phone every time you want to replace one. I'd recommend something like this:
http://www.amazon.com/JustMobile-Gum-Pro-Power-Pack/dp/B0026NB4UE
4400mAh (presumably at USB's 5V) capacity and a full 1000mA current for charging other devices. Just ordered one myself because the Desire's battery life is so awful (apparently mainly because of the AMOLED screen)

U have to turn off your phone anyway to do anything: switch sim, sd card or battery and it takes u up to 3 mins, thats not a lot of time wasted.
@ the user above:
I had the same problem my desire not holding for long and i wiped battery stats and my battery life doubled. Besides, adams rom is without sense so i imagine a lot les data runs at the same time in the background, which enlenghtens the battery life.

Using w7 MCR ROM with minimal apps added and other apps removed that I don't use and battery life is barely 24hrs with the latest radio...using the old MCR 2.2 ROM with the leaked radio I was getting 2 days with the same usage so looks like a radio issue to me...

Why would you switch your SIM card or SD card regularly?
I just leave mine in there unless I get a new one - which is about once every two years, respectively

I know it's not official HTC Froyo, but should give some idea of Froyo power consumption...

Let's do some investigation !
The problem:
Many 2.2 roms with HTC sense complain for a very low battery life. The problem seems to be the following: when the screen is on, the battery melts (!), 1% per every two minutes approximately. The sleep mode is okay. So far we don't really know what's causing this.
A way to find the solution ?
Maybe we could do some investigation to find out which process drains the battery. I propose that we use JuicePlotter (or battery graph, never mind), try to kill some processes, and analyse the pitch of the battery level graph.
I'm going to work on it right away, but we can do it faster if we are several persons to search.
What do you think ?

You've already found the solution: Screen on, battery dying => AMOLED is ****. It uses way too much power...

Don't think so... In my battery stats, we can read:
Android System: 40%
...
...
Display: 8%
Moreover, there is no such battery drain with 2.1 HTC roms, or vanilla 2.2 roms.

Wohaaa. Android System shouldn't be over 10%... your system is doing something strange. You could try monitoring CPU usage with System Panel (search the market) and try to locate the culprit there.
Otherwise, wipe and reinstall...
Or are you telling me this is the case on all Sense ROMs? That can't really be, there would've been mass panic in the streets and a lynching of all HTC CEOs
-edit- Although... did you leave the screen off nearly the whole time? And didn't use the phone at all? How much battery life did you get out of that charge?

Thanks for the advice. I checked in Android System Information, and android.process.acore is pretty much always at 100% CPU . Is it normal ?

Most definitely not. Should be practically idle most of the time. Try a reboot, and if that doesn't work, a wipe. Back up with Titanium Backup first and restoring after the wipe won't be such a pain...

More Battery Testing on the SGS2, Stock batt VS Ankler

Hello forum and its inhabitats ! I have a new issue today (a new thread about it at least, the issue was here always); battery capacity and the SGS2 battery life ! My GS2 was sent with a 1650 chinise battery -- im not very happy with it. Using the phone quite passively leaves it with only 6 hours of battery life - i checked and it was roughly 20% per hour -.-
So i was browsing ebay and stubled on battery replacers for the GS2, one of them being a 2430 mAh capacity battery (http://item.mobileweb.ebay.de/viewitem?itemId=130594902895&index=14&nav=SEARCH&nid=15065655277).
So i wanted to ask, is it a fake ? Which battery should i buy to prolong my phone's life ? Thankyou for anwsers by time ^^
Sent from my GT-I9100 using XDA App

Oh and what i want is an extended battery without having to get a bigget case or anything. And, should i buy a 1650 again, just the japanese version ? Come on people i know you can anwser this
Sent from my GT-I9100 using XDA App

The Anker 1900mah battery (amazon.co.uk links: single battery, two batteries + charger) is probably the best extended battery which is the same size as stock (no bigger battery cover needed)

20% battery per hour is not normal with whatever "passive use" means. I would first investigate what's using up your juice before getting a new battery. Go into Settings -> About phone -> Battery use to see what's going on. Your phone might not be getting into deep sleep in which case BetterBatteryStats from the market might help you.

Yes its fake, only buy original samsung batteries, samsung has a larger 2000mah battery if you want more capacity.

Yeah, the screen usually eats 65% of the total battery. Where and what should i search in this betterbatterystats ? (downloaded it already).
And yeah, not quite passive use i'd say ^^
Sent from my GT-I9100 using XDA App

Well, if the device loses 20% per hour, its probably not going to sleep.
When looking at the battery stats (settings > about > battery), try to see if the device is awake a whole lot more than the screen is on.
If it does, with betterbatterystats you'll be able to see by going to "Partial wakelocks", whats the cause of it. if an app has a long wakelock time it is probably the issue for the battery troubles.
try to see if you have facebook sync, maybe its causing it as well.

Im gonna run System Monitor today, to watch what apps used what and how much. Plus BetterBatteryStats at the end of the day. Lets see whats wrong with this phone <.<
Im also using Revolution ROM (2.7.1 i think..) with the CF-Root kernel. What i turned on by myself is: screen brightness minimum, sync of Gmail and Twitter (quite often, twitter every 5 minutes and Gmail i dont know how much. Constantly i think). Gtalk is always on, Mobile data is always on too, i do some browsing at times and some games too (at a higher screen brightness usually). AVG antivirus is always on, Latency is updating my position, Evernote large widget (the only widget im using, everything else is shortcuts). And thats it.
I know it may seem much but i still think it shouldnt be eating THAT much. Especially when its screen is off for 4-5-6 hours per day because of school.
Im also gonna post the apps that shouldnt be running in the background this evening (im from germany)

Ok so for now it taked 10% per hour with me not using it much. Lets see what stats i get at the end of the day. What exactly should i screenshot ? I got system monitor, BetterBatteryStats and the stock battery stats.

Eh.. I think i'll do the run tomorrow and post tomorrow's stats. Today my phone crashed once, and i turned it off once aswell, so i have a 30% gap in all monitors (from 70% to 40%) soo yeah.. Post your suggestions, people.
I'll test out this battery, and then fix some issues and test again, then do the same to the 1900 one higher in this thread to see the differences

Today's results:
-unplugged this morning at 7:33 - 100%
-plugged in right now at 16:23 -5%
So roughly my battery lives ~9 hours per day. Why im still not happy ? Because im not using it the half of the day due to school, and when i do use it, the discharging is a bit overwhelming in my opinion.
Turns out it drains 11%/h or so.
I'll post the numerous screens from different applications, hoping that peoplr will help me improve the battery (since i know a lot of other people have their phone living for 20 hours !)
Also, you will notice the skip in the stock battery monitor and in the system panel app, its just how i said in my other thread - data loss. I was reinstalling chainfire so that the tegra game would work, and ofcourse the phone rebooted forcefully after installing/upgrading the CF3D plugin.
Stock monitor (approx. 1 hour of data was lost):

Odd: Those two Bluetooth services
None of the next ones should be running in the background in my opinion:
None of those eighter:
These too shouldnt be here ?
Samsung keypad i understand, but i didnt knew it always runs in the background. Others i dunno.
WTF Skype, i haven't opened you in weeks !
Those that are EX here i know they should be working.
XDA runs in the backgroud ? With otifications i guess yes, but i had none untill now and will turn it off. Also, system apps begin, and i wont comment on them
Except for this one maybe. I have my Latency location updating, so that explains the friends location

Sorry guys for the overload of screenshots. I dont have a pc now and wont have one soon eighter, so its hard to type and go back and forth to check every apps name, usage, cpu time ^^" plus this is another reason why i need my phone working at its max, life longerso i could use it normally, but not hold it on the charger constantly.
UPDATE: today my screen (when it was used) was at 20% brightness, and i deleted the twitter account, so no sync every 5 minutes (i still dunno about GMail, maybe its constant ?)
Also ! I dont think my screen really used just 48%, its usually more - around 60% ! And today i actually saw that it was 73% at some point but then it would fall down to 60 again due to idling (probably the data was lost. Again.)

if you are looking for a new battery, the anker 1900mah is the best you can get without increasing the size of the phone! It is also the only third party battery that is proven to be the mah they claim it has, some even get 2000mah with this battery.
If i was you, i would first disable all your widgets, and then check again! If its a big difference, add them one by one slowely! Some widgets can cause battery drain. If that doesnt help you can try to reset your whole phone back to how you got it in the beginning and then slowely add your apps back.

Battery Failure Issues

As stated in the title, my device is having battery issues. I tried posting in the dev thread for the rom I *was* running, thinking it was a problem with the ROM but it turns out it isn't. I'm seeing the battery randomly report 0% and the phone instantly shutting down. I am then able to reboot, and every reboot will show a gradually increasing battery level, from 0% to 70%. I am currently running the P.A.C. rom, but I was running the CM10 port by dman. I was originally told this issue could be from a misbehaving 3rd party app, but I am running brand new P.A.C. without any 3rd party apps installed.
Here's a picture of my battery stats from CM10. PAC is the second one.

I've read that it may be a mis-calibrated battery meter, but I've done multiple charge cycles since this issue has begun. If anyone can shed some light on this, I'd really appreciate it. This device is my daily driver, despite running development roms.

I myself have noticed my battery is losing its charge on its own. I charge it to 100% then remove it from the phone and put it back in 6 hours later and it is down to 90%. I bought some other batteries from ebay and they keep their charge when not in use so I think my original battery is dieing. I recommend you do the same test and see if it could be your battery.

I'm thinking my battery may be faulty but the weirdest part is that it rarely fails outside of school. Whenever I'm home it lasts hours on end, but the moment I get to school it starts freaking out. It's probably just coincidence, which is why I didn't mention it in the OP. Just wondering, dudejb, when did you get your phone? Mines under a year old.
EDIT: Uh... well, the phone was acting odd, with the screen blacking out, so I pulled the battery, and the phone was running without a battery (plugged in) for about 40 seconds, and it didn't detect the battery was removed. Then it crashed. I'm seeing weirder and weirder things happening with this phone... D:
EDIT 2: Well, it crashed, rebooted by itself, and has now been stuck in a boot loop for the past 20 minutes. :I And I still have 2 years until I can upgrade my phone...

Last year around this time December. DO you have bad reception at school. this can effect the battery as it keeps looking for a signal.

In some areas, but none of those areas are where it dies. Actually, you can see in the battery stats picture (the PACman rom one) That I have a good signal when it drops. The mobile signal bar is green when it drops.
Well, I've managed to cause it to reboot itself while streaming the logcat to my desktop via ADB, and the original error is completely blown out of the buffer before I can cancel the output. :/

Well, simply as an update, I rarely used my device today, and I had 0 battery issues. I had the clockspeed gov set to conservative, and only lightly used the phone (calulator, calendar, etc.). Battery was 60% when I got home after approx 8 hours off charge, instead of needing to be recharged after 5 hours. I don't know what I did, but it seems my specific phone is just unstable under heavy use. :/

Hello.
I have exactly the same problem. Everything is ok if I don't use the phone, but if I listen music, play a game or surf the battery indicator can go instantly from a XX % to 0%. This issue started with the coming of cold here, maybe the battery is dead ?
It is impossible to restart the phone after, unless I plug it. When I reboot it, some time it indicate 0%, sometimes the same XX% before it shutdown.
Sometimes when I plug it, during a short time, the XX% decrease (!!!) instead of increase.
I tried to recalibrate the battery with CWM : no change.
Edit 14 January 2013
I just got my new battery, everything is ok now.

Same problem here as well. I'm planning on getting a replacement battery to see if it will fix anything.

I'm blaming the prob at the battery! my wife's phone is having the dame prob, switched batteries to mine and now I have the issue!!
she would never let the phone fully charge, it would go till maybe 5 to 10% then she'd charge it to 50% and go again! I'm thinking that broke the battery! mine lives on the charger at night. usually last me all day sometimes it's only at 40 to 50% by the end of the day, when I get ready to sleep, it goes on the charger!! done all my phones this way and they last! never had to replace a battery!.
Of course this is only the 2nd half computer half phone I've had!

The battery is the issue I just bought a new hyperion battery 3500hz and its fixed my issue
---------- Post added at 04:54 PM ---------- Previous post was at 04:51 PM ----------
The damn phone kept saying it was still good and I just couldn't figure it out but that damn battery was the issue after all... so just buy her a new battery, I got this one for about $18.00 and its already doing so much better and charging like it would normally

Its using the same charger I had to begin with it just takes a longer time, I charged last night and was on facebook all night forgot to close out, made several calls and been online and only down to 64% right now. The size of the backplate makes the slide out keyboard easier to use as well, my big hands find using it easier now.

I had the same behavior and it was in fact specific to my battery. I have three batteries, so it took me a while to single it out but after worrying it was the rom(s) I found that it was just the one battery, which was an OEM and not one of my cheap chinese ebay ones. I would give a new battery a try for sure.

Exactly. It is unusual that the battery status seems off by ics or gingerbread.. it was concerning until I zeroed in on the problem.
It is likely the battery.

My wife's phone just began having this exact same problem. She is running the newest ATT ROM, no mods, no root, nothing. It began about a week ago. The battery will be at 65%, then all of a sudden, 0%. Leave it off for a bit, turn it back on, and it's at 30%. I've also noticed it's draining really fast. Went from 90% to 50% in the span of half an hour.
I was going to try a calibration or even a hard reset, but from what I'm reading here, this is a battery issue? She doesn't want an extended battery, and still has six months until her upgrade. Any suggestions for a fairly cheap aftermarket? No way I'm getting an OEM replacement with the original having this problem. Sounds like the control circuit is fried.

I can confirm that it is the battery. I had to replace mine and I was one month past my warranty.
My battery was swollen. Take the battery out and put it on a wooden desk. Spin it like you would as a bottle (spin the bottle game type spinning). If it spins, yours is too. At&t will replace (for free) it as its a common issue if you're under warranty. If not, you will have to buy one yourself.

Mine was one month past too. Easy solution: went to the retailer we originally got it from, bought one (a Glide) outright, swapped the battery, and returned it (the Glide). By the time this battery fails, she'll have an upgrade.

Same issue some months later with my new official battery.
In the same time, screen is gone crazy like it was being controlled by other people than myself...
I will order an extended battery on eBay now...

Battery percentage setting issues

Hi again,
Just about to give up on this tablet when I noticed that it seems to be the battery percentage setting that is causing my charging and discharging issues.
With the setting turned on and the percentage visible, the battery seems to discharge and charge oddly, and also the percentage shown does not reflect the amount shown on the battery icon, or at least it rarely does, but it varies.
With the percentage setting off, the discharge seems much slower and predictable.
If you have a p600, could you possibly try this for me with and without and see if it matches with my findings?
Thanks.

I'm having very odd battery issues myself. I'll give this a try and see if it improves for me.

With it on I have noticed............ If I remove charger at 96% next thing I notice battery is at 100% and my battery app charts that jump.
I'm using Battery HD, are you using a battery app also?

Thanks for the reply. I'm not using any battery app, just the one that comes with the stock tablet.
I think I did encounter the same thing as you, and also unplugging at 100%, then taking it upstairs and looking and it was 96% or so, and then after a restart, it was 100% again. Very odd, but it doesn't do it for me unless the percentage setting is enabled.

No i suspect my device might have some deeper issue. I can drain the battery from 100% to 0 in an hour of playing games but if i turn off the note and turn it back on, it'll be back at 60% or whatever it's actual battery level is. I can rinse and repeat and slowly get it down to 0. Either way the battery drains much quicker than it should. It could probably only last 6 hours of screen on time with very light usage. I might need to get motherboard or battery replaced.
I am still hoping that its a software glitch and something like this could fix it.

Yeah, mine wasn't that bad, although bad enough. Hopefully you can find a fix without having to send it back.

I wonder if the tablet needs a little time to calibrate the battery usage, maybe there is an internal process that has to happen over time?

I've had it since it was released in october or november and the battery life used to be good and last 10+ hours and probably 5-6 hours while playing games. Not sure what happened in between. It has taken a few very light drops with no visible damage and i did break (bend) a charge with it in the tablet but the charging port seems normal and still works fine.

Just checked with battery % off for 30 mins and battery dropped 4% which is normal.

I still had crazy battery drops with the percentage turned off. so didn't seem to make any difference for me.

Is your unit still rooted????? If so have you tried removing root and installing the most current factory rom.
Have you seen this post "Longer Battery Life (or How You're Being Robbed!)"
It may help some that are having issue with battery drainage but after seeing your post #36 in the BATTERY posting .... I'm leaning towards a cracked or damaged board from the few drops you talked about.

I've tried unrooting and odined back to a factory rom, also cleared my SD cards, nothing helped so i'm back to being rooted for now. I've done a lot of the tweaks to improve battery life but whenever I play games, it just drains like crazy even with minimum brightness. The drops were very very minor, like from 1 foot onto carpet and with a case so I doubt that it was the cause but I guess theres always a chance.
I'm still wondering if I should just live with terrible battery life and stay tethered to a charger or risk sending it back to samsung and having them find out it was rooted and overcharging me for repair. And I love the device so much, I don't know if I'd want to give it up for a week or two.

Tested again last night and this does seem to be the problem on my unit. Just over 2 hours and the battery icon had barely moved, and looking in the settings, it showed that I had 84% left. Hopefully it wasn't a one off.

Thanks :good:
So, I wonder which is correct, the icon or the percentage? If the percentage is right, my tablet is faulty. If the icon is right, it would seem to be ok.
And all these reviews and people that get 10-12 hours, I guess they went by the icon?

The percentage gives a more accurate time I guess.
But people and myself use the "Screen on time" as the usage data.

Was doing ok last night and then came here and the battery took a dive. Went and grabbed adblock for firefox and ghostery and ghostery was reporting 65 trackers on this site. Also the malware popups were becoming ridiculous and they only happened here. Going to do a factory reset and not come come here tonight, see if that helps anything.
I did do a bit of a search regarding the malware here, and it was being reported as early as last june it seems.

Battery Sudden Drops

Dear all,
Recently my Note is facing a weird problem. While my son is playing a game, the battery drops 20-30% in 10 minutes. If I shut down the tablet and re-power then the battery goes to normal again.
In the battery stats I can see a huge drop during game usage and then up again on reboot.
I performed a factory reset but the same happens....
I flashed the Kit Kat via Odin.... but the same
Any ideas?

Drain the battery down to below 5% then charge it to 100 and it should be fine. It happened to me once and after a full charge after a full drain it never did it again

This is what worries me.
I drained the battery and charged it fully powered off. It did it again. I drained the battery and charged it fully powered on. It did it again.
If I'm using it for browsing, papyrus, images etc its fine. This happens only in games and when i reboot the battery percentage is ok again.
strange....

I had the exact same problem as you are describing but additionally, my overall battery life wasn't lasting as long as it should either. I ended up sending it to Samsung's repair center to get fixed. I'm not sure what they did but some other people on the forums suggested it was a motherboard issue.

So the capacity of the battery seemed just fine but the readings were crazy (dropping from 50 to 5 in minutes and then on reboot back on 50).
After 2-3 full cycles of charging nothing changed. Flashed fw nothing changed. Went to Samsung service and they just informed me that they changed the battery and now performing final checks.
Hope this will solve the issue. I'm too lucky that I am in the "6 months warranty" window for battery...

How does one go about sending it into Samsung? After getting it back, did you see a significant change?
I've been debating doing this but wasn't sure how to go about it.

I haven't got it back yet. They just called me and they said that apart from the battery, they need to change another part (the telephone operator didn't know which part) and I'm going to receive it tomorrow.
So I'll let you know once I receive it.

After trying everything (flashing different roms via odin, factory reset, full battery cycles etc) the problem never went away.
Went to Samsung service. They checked the battery and had to replace it.... within the warranty.

Same issue here. Just got an email saying its fixed. They changed the charging port and lcd. Weird that they replaced the lcd.

Well I got it back. Seems they broke the s pen function when taking it out or putting in. The tablet thinks it's always out of its slot. I guess another 2 weeks without this thing. What a pain in the ass. Times like this makes me wish I bought an ipad where I could just walk into the store and get it fixed that day.

I had the same problem. I sent it back on Monday and got it back 7 days later. They did not say what they changed, but now everything is working fine. I even got a new usb cable and a magnetic Germany flag

I sent mine in for an overheating problem and they changed the charging port and gave me a new cable. I initially also had the random drops in battery but seems to be better now.. They said bad voltage going to charging the battery or something. Still have overheating so gotta send it in again?

So guys did you get it fixed? I have exactly the same problem. I have sent it to fix at the sam service - they changed the charging port, but it didn't help anything. 1,5 years of normal usage and now I can pretty much throw it into the toilet. God damn POS!

Galaxy Note 10.1 2014 battery drops
Hello all,
Just wanted to inform you all that I have been experiencing these battery drops (yesterday from 93% to a mere 5% in a matter of minutes) for a very long time now. I am running under the latest 4.4.2 stock firmware.
Also, battery life is way below par (understatement !), where the Note sometimes drops to around or below 5% (the magic number below which the screen starts to dim pretty dramatically and there's no way to influence that)
Funny thing is that after the battery drops to below 5% or even 1 or 2%, it's still possible to use the tablet for quite a number of hours afterwards, which suggests it may be something with the logic estimating/determining the remaining battery capacity, rather than the battery itself....)
Now I've tried draining the battery and fully recharging it multiple times/ resetting the stats using free apps / revert to factory settings etc.
All to no avail unfortunately, this problem simply keeps coming back.
(By the way: Apart from the battery and battery life, the Note is an excellent device, and delivers as promised.
Please also note that charging it through the microUSB cable is also simple, stable and relatively fast, unless you compare it of course to my all new Samsung Galaxy Note 4, which has a superior fast charge mode and offers the highest possible battery-life at this moment and easily beats any other smartphone (including the usual suspects from that Cupertino-based firm of which I can't force my mind to remember the name of.....) in this price-quality and performance category )
As for warranty:
Battery is no longer under warranty, the device itself is.
As such, I will now get the battery replaced by a new Samsung OEM-battery first, and see if that resolves the issue.
If it doesn't help, I will send it in for repair for Samsung.
I will keep you all informed on the resolution and cause.
Likewise, if there's anyone that has gotten to the root cause of this issue, please let me / let us know
Some users reported some 'magic part' OTHER than the battery itself (motherboard / charging circuit or even the lcd ??) having been replaced by Samsung after sending it in for repair.
That information could be very valuable to us all in trying to get Samsung to resolve the issue, so I would really appreciate it if someone would share this info in this thread.

Hey I know that there hasn't been much activity on this particular thread, but i too have been experiencing this problem for over a year now. I sent it into samsung twice and it still never fixed the issue and by the time i was going to send it in the 3rd time it was out of warranty. I personally removed the back cover and unplugged the battery for a while and that did not help. I have tried flashing different ROMS and kernels to no avail until last week. I flashed Temasek's Unofficial Build found here http://forum.xda-developers.com/gal...t/lt03wifi-temaseks-unofficial-build-t2980604 and after 3 full power cycles i have not had a single random drop yet i even managed to go 3 days with 6 hours of screen on time which is a record for me with this device. Not sure if it will help everyone but this seems to have solved my problem and i am thrilled! Also (as embarrassing as it is) i played 2.5 hours of Clash of Clans straight without a single random drop either.

I am beginning to have the issue as well on my P605v. Has there been any progress with your battery replacement? @mroset

Hello KwestJones,
I've successfully replaced the battery in the Note 10.1 2014, and it has improved things. With a little care, this is easy to do. Just removing the battery connector is a bit typical, you need to lift it carefully and slightly to remove it.
The result is not as drastic of an improvement as I would like to have seen, but at least the sudden drops in battery capacity percentage seem to be under control now.
I am doing a video test now, and will see how it behaves and let you know.
BR,
Maarten

Very curious to hear if replacing the battery corrected this issue. I've been experiencing this same battery drop issue for 2 or 3 months and the unit is well outside of warranty. Hoping there's a simpler fix, but willing to replace the battery if that will work since the tablet itself is still a great unit.

Complete factory reset should clear the Android Coulometer's data base or learning algorithm. Just clearing options of Battery Monitor Widget for rooted devices won't help. There are some other apps, which seem to help if the charge level never reaches 100%, a related, but not identical problem.
I have an old tablet suffering from this, with a tweaked custom rom, and i didn't want to clear and setup that completely. The algorithm or database is "learning" again, and the capacity jumps have become fewer and smaller over the last months. It should depend on how long the device was used and never reset before the incident. In my case over a year.
Itvs much like my cars fuel calculator, which won't work correctly during traffic light stops. Right after starting the engine, fuel consumption can raise several liters/h, when the car don't drive, as it uses the last sampled value(every 30 meters). And you need several kilometers to drive to have these levels drop to realistic ones again. While after a long driving distance, a traffic light stop will hardly have an influence.
