Hello there,
I would really like some advice - my battery is draining like water. I'm quite convinced it is the regulation of the unit; I bought a 2400mAh battery replacement and it lasted ages on first go, but then my G1 started draining stupidly fast after I'd recharged it. This also happens on the stock battery too (buy even quicker!). I'm convinced it is the regulation because a) I've never had battery problems previously and b) the battery meter starts at about 26% when I plug it it in (after the phone shuts off from it being dead and I then plug in the charger).
I actually have a bricked G1 that still charges batteries, so I thought I'd do an overnight charge on the battery that way, to 'remind' the other G1 what a 100% battery is like, but that didn't seem to work either.
Can someone help? Is this a known problem? I would really appreciate any advice.

Things that cause ridiculous battery drain;
Backlight, keep it at no more than 30%
Wifi - turn off search for open networks,
Gps - wow does this drain

GPS doesn't really drain battery unless it's actively being used...at least not on my phone.
You can also try disabling 3G if you're not in a 3G area. It will keep trying to find a 3G signal, which really drains battery.
For the record, I have a stock battery that I get ~13-16 hours on from a single charge... my backlight is at 40%, GPS is always on, and I use wifi whenever I want to surf the web and am near an open network.
OP...if your battery is lasting you only a couple of hours, then I'd try to reflash your ROM. Might help...
Wow 13 to 16, I am lucky if I get 6 with 30% backlight, and wi-fi and gps off, I have always gotten that on ever rom even stock with no widgets, you are one of the very few with good battery life cause I have seen many complaints about short battery ranges

Yeah, that's on a normal, moderate usage day. If I use it heavily, with a lot of wifi and web browsing, then I'll get around 10.
Maybe your battery needs to be replaced... could just be old and not holding a charge properly.
It's 2 months old, has done it from day one, I also have another battery that does it too that I kept from a previously brick g1, so one 3 phones, all the same battery life but then I use it quite heavily, always browsing on the web since my computer burned out

try that? 3rd gen battery could help..
Thanks for the suggestions, but it's not a wifi/3g/brightness etc problem - I've had a G1 for six months, I know exactly how much power should be consumed. It's also not the battery; I have two stock batteries and a brand new 2400mAh battery, which for the first few charges lasted about 2 - 2.5 days and was brilliant (as it should be), but now doesn't last all that long.
I may have made the situation slightly better however - I did a Nandroid backup, wiped to factory (well, Cyanogen 4.0.4 anyway) and booted into that. I then restored the backup and when I plugged back in to the charger, the meter was at 85%, and seemed to take a normal amount of time to charge (and not jump to 100%). It remains to be seen if the problem is solved, I've yet to have the battery drain (this is a good sign though) an plug in the charger to see if it will jump from 0 to 25 or not.
I'll re-post when I know.
run the battery down until the phone shuts off without plugging it in.
charge the battery while the phone is off over night
do this 3-5 times and see if you get any improvement.
also remember some of the cheap 2400 batts from ebay and such claim 2400 but that is from 3.5V to 3.0V. The G1 considers 3.2V to be dead so you only get from 3.5V to 3.2V which sucks.
I'm with gridlock on this one. My batteries suck. It always needs a mid day charge. And to the poster that said to reflash a rom, that is bad advice. There is known issues with getting poor performance out of these batteries. I have 2 and both do the same. Got the second one from complaining to t-mo about how bad it sucks.
Reflashing seems to have worked...the 2400mAh battery seems a lot better now, it lasted nearly two days (it runs at 3.7v, according to my battery diagnostic), I've only just recharged it last night. When I plug it in, it charges normally and linearly now, instead of jumping straight to 25%.
So my advice, if anyone is having similar problems to me, would be to try a reflash.
Thanks for your help everyone.
OK, I've had my HD2 since November, and I've never understood people who complained about poor battery life. I've consistently been able to go up to 2 days before charging. On the odd occasion, I've left TomTom running and it's drained the battery right down, but overall I've been pretty content with the battery performance.
Until about a week ago. I thought I'd maybe forgot to stick it on charge overnight the odd time, but now realise the battery has started to drain much more rapidly.
I did not change ROM, or install any additional software. I made sure nothing was running that shouldn't be in Task Manager. All of a sudden, I'm getting quite random battery drain - up to 20% drop in an hour. I put up with it for a week, thinking it just needed a hard-reset, so last night I decided to flash a new ROM. I updated to the latest radio ROM, and flashed bobsbbq's latest ROM thinking that would sort it, but after I took it off charge this morning it was down by 15% within an hour.
The drain has levelled off throughout the day, but it's still much higher than I'm used to. I don't use wireless, and I only have bluetooth turned on if I'm on AC power, so I've just got GSM/3G in normal use (and get good reception at home and work).
The fact that the battery drain changed so much in such a short period of time, with no obvious change in usage or software leads me to believe the battery itself is beginning to fail. I usually expect a good couple of years from a mobile battery before I see noticable drops in charge, but that's 6 months.
Is it possible the HD2 batteries are not very well made, resulting in some people having great battery life, and others complaining that it's crap?

I had read that some of the HD2 batterys were a bit dodgy as they were siphoning off the batterys from different manufacturers and as a result some are remarkably better than others.

I am precisely in the same boat. I am using my battery now for around 6 months. Since last week the battery seems to drain much faster than before. I am still analyzing what could be the reason, but I think it's the battery itself that is getting weak - far too early.

You said it yourself, the batterys performance gets worse for every day and should be replaced with a new one every 6 month, atleast.
Some feedbacks in other threads pointed out a possible and unforeseeable cause, the microsd card.
Try removing it and check battery drain, if that's the culprit try formatting it before throwing it away.
Also, as I stated in at least 3 other threads p) it's always a good idea to check battery drain with battclock, it should be 4mA during standby, any big variations from that mean something's draining while phone should be sleeping instead.

Yeah mate, that's laughable. I've never had a mobile phone battery go within 6 months. Are you trying to jump start your car with your batteries or something?
So i recently flashed CleanDFT ROM, first couple of days the meter read out 1 day and 18 hours which im very surprised then it went down to 1 day and 4 hours, now this morning i unplugged and it tells me i got 19 hours left from full charge, should i go by this? or is there something wrong?
hello can you help me wid flashing...i came from android...no idea of how to do it...

Redirecting you to the right place.
If you have just flashed a new rom, in general, you need to go through a couple of battery cycles before the battery read can be accurate. I remember when flashing my ATT FUze I had to wait 2-3 complete charging cycles ie. discharging battery to 10% and charging back to full before I could get accurate reading. If you are experiencing worse battery time than before flashing after 2-3 cycles you might need to reflash the rom; you should see better battery time with custom roms, so I have heard.
I also wouldn't go by the battery saver timing, I would go by wpbench or real time use to get an accurate reading on battery time. I have a 1800 mah battery in my focus and it reads 24 hours on battery life
As far as i know, doesnt all the ROMs have basically the same battery life?
Ill be going out of town sometime this week and ill be out most of the day, i need a rom thatll at least last a whole 12 to 14 hours at the most or whole day at best of just occasional twittering and occasional checks on facebook and probably capture some pictures and a video and maybe an hour at most on music? im sure this phone can handle it but idk what you guys suggest
I have the same issue with ATT samsung focus with Roger latest updates, the battery meter is just not accurate, sometimes full and just reboot upon eject from the micro usb. The battery was fine until recently. Found a few other with the same issue online, no solution available yet.
*pulling out battery doesn't work*
The solution is exactly the same as it is on a laptop.
Lithium ion batteries, and, actually, come to think of it, pretty all rechargeable batteries lose capacity over time. The phone, to begin with, doesn't have a good idea of how much capacity is left, and it has to estimate based on previous performance. This is partially a result of battery manufacturers going as cheap as possible with the circuitry in lithium ion batteries.
The phone needs to figure out how old your battery is. This data is definitely lost with a new rom. Leave it to charge overnight, then unplug it and let the battery run all the way to dead. Charge it again, and your battery percentages should be correct. It may take more than one cycle, but the meter should settle into a correct estimate eventually.
Incorrect battery stats are a possible reason for fluctuations in battery life and reseting them as described in the previous post can help.
Another thing which you can do is use an app like this http://forum.xda-developers.com/showthread.php?t=1328730 to check the reported mV rating of your battery at full charge. That can serve as an indicator of the battery life you can expect with your current battery stats.
Last week I got a new battery installed in my Nexus 4. I was using the original, around 2 year old battery, and I found it would drain very quickly below 50%. I had a shop install the new battery for me, I don't know if it was an official LG battery or not.
I ran the battery down to zero percent my first night with it, and have charged it at night ever since.
When I unplug the battery in the morning the battery percentage will suddenly drop down to 88-94% in about 1 minute. After this the battery drains normally and I get good battery life.
Today I tried charging it back up to 100% after it had dropped to 88 %. It charged to 100, and drained normally down to 95. Then, in a minute or two, it dropped down to 84, and has been draining normally.
Battery life is good, but the strange behaviour makes me think something is wrong with the battery. My question is: is something wrong with this battery, or is this normal behaviour? If it is, than I can ask them to give me a new battery. All this is with the stock ROM. I flashed 5.1 since getting the new battery.
Exactly the same here: Old battery made a worn-out impression, so bought a new one. Actually tried three different new ones from ebay now, all do the same: They charge up to 4.3V around, and when unplugged drain to 87% in a few minutes, i noticed the voltage going down to 4.0/.1V mostly, too.
The current battery seems ok from battery life, but i want an even distribution of the battery status, no matter the voltages - how can i achieve/fix this?
Same here.
Are there any solutions for this issue?
Hi everyone!
I got a Note 4 a few days ago and it has battery issues.
I got it second hand online from a guy I don't know. I'm from Romania, I think the phone is from the UK, it's Verizon branded. The model is SM-N910V and the Android version is 6.0.1. It's not rooted. I noticed this V version isn't very common.
The battery that came with it was pretty poor, it would drain in a few hours with minimal usage and the worst problem is the phone would suddenly shut down at about 30-35% battery life. Then it would go into a booting loop, without being able to actually boot until I plugged it in.
I bought a new genuine battery from a popular online store here (F64), battery life is better, but still with just wifi, it went to 50% in about 2 hours of browsing. Without wifi or data (very little), it lasted for a day and a half. But the phone suddenly shut down at 8% battery life, again going into a booting loop, without being able to actually boot until I plugged it in. I'd also like to mention, when the new battery came, it only had 4% battery life left (I heard they should come about half charged, is that true?) and also there were a few reviews from people who had to try multiple batteries from this store until they got lucky with a good one. Both the old and the new batteries look identical, I don't see any signs of counterfeit.
Should I return the battery and try a new one? Is there a chance there's something wrong with the device itself?
Thank you very much!
Common problem.

Return the battery.
The seller store the battery in a very poor way.
Lithium should be kept at around 40% charged if you store it for a long time (more than 1 month)
I have 5 batteries with me, 3 of them are considered broken (70 - 60% left)
The last 2 are still in very good condition, around 98 - 99%
About your device, you will need around a few days of charge cycle with a good battery.

Thanks for your answer. I didn't know batteries for this phone are so problematic.
I just charged it to 100% slowly from my PC, will use it normally and see how much the battery lasts and if it shuts down again. As I went through forums, some people say I need to do battery calibration. If it's still bad, I'll return it.
Thanks again!
Try to get a battery direct from Samsung. Failing that buy a PowerBear or Anker. Do a factory reset and calibrate your battery by fully charging it, then running it down to 0% (if it shuts down, keep turning back on until it won't turn on). Then charge fully back to 100% again - DO NOT USE FAST CHARGE.

I will look for a store somewhere. I don't think I can find those two brands here.
I did a factory reset when I bought it a few days ago, but that was with the old battery. Will do the factory reset after I drain it to 0% later today.
I don't have a 'fast charge' charger, and I have it disabled in settings.
Thank you for your response!

What I said before is for all phone that uses Lithium Battery.
Lithium Battery must be kept in a storage at around 40 - 80% charged & must avoid hot places if you don't use it for a long time.
Draining Lithium Battery to 0% will deteriorate the battery faster so it's a big NO.
Calibration is done on the phone not the battery.
Delete "batterystats.bin" to calibrate the battery gauge.
Calibration is useless if the battery is bad (you received it at 0% it means that the storage condition is bad thus the battery is bad.
Charging from PC is a BIG NO as USB port on PC only provide around 500mAh & usually it's unstable.
The charging rate is too low & it could deteriorate the battery faster too.
And the last....I think factory reset doesn't necessary reset the batterystats.bin, so you have to delete it manually if you are rooted or follow this link if you are not rooted.

Hi, I didn't return the new battery after all, I think it 'calibrated' itself after the first charge. Also it goes from 100% to 1% and shuts down properly now.
I did two tests on full battery:
- barely using it, no wifi, data etc, just a few short calls (probably 30 mins of OST) and it lasted almost 6 days
- stress test, wifi and data on, gps with maps and waze on, maximum brightness and and a very long youtube video playing constantly (screen on) and it lasted about 5 hours and 30 mins
In normal use it lasts me about 2 days, but it slightly worries me that if I keep mobile data on all the time it only lasts until the end of the first day.
Would this be considered a good battery life for the Note4?
Thanks to everyone for replying and helping!!
