Battery Issues/Not discharging to 0%/terrible life - LG V20 Questions & Answers

VS995, Rooted, been running WETA since last January.
------------
About 2 months ago I noticed whenever my phone got to 15% battery left when I plugged it in it would reboot. I ignored the issue for a while because I rarely let it get that low.
Recently though I notice my battery life getting very bad. Insanely bad. Not even 2 hours of SOT, dying in 3 hours just using hotspot with no SOT. Losing 10% in a few minutes of active use sometimes.
So I tried some battery calibration apps, tried recharging to 100% and draining again. Tried wiping battery stats. Tried different ROMS.
I flashed desolation ROM tonight and the battery life seems to be really good on it but it ended up shutting off at 24% left.
Battery apps say my battery is in good health, but I'm wondering if the battery itself is bad? Any tips or advice or help of any kind is appreciated. Thanks

I just wanted to make sure because I've never experienced this issue before. I even hand my smartphones down to my mother and they tend to get over 2 years of use and I've never had to buy new batteries. Thanks for the feedback

If it drops from 24% to 0 then im pretty sure its a damaged battery try it ypu can buy it for less than 20 dollars on ebay
If it drops gradually in standby you could have also a battery drain bug but this is not the case here

How I fixed My Battery drain

Hi!
I've made a n interesting discovery with my battery.
3 weekends i have drained my battery until it shut itselfs off, and then i have charged it up again. And now i realy can live with my HD2 battery life.
When i come home from work i have about 80% and now as i write i have 76% left at 20.44.
Before i would have about 30-40% left at this time, i have never drained my battery before to 0, so when it happens the first time i noticed a slightly improvement. So the next weekend i did the same, and this last weekend i unplugged my charger at 06.00 in the friday morning and did not charge before sunday morning at 10.00. And for me THAT's a BIG/HUGE improvement.
Glad you resolved your issues .
I've found that having any kind of TSR apps installed on the device memory instead of the storage card, has made the battery life livable on my HD2 .

Hey guys!
I really need to try this. my battery life is just so pathetic.I hope it works for me too.
TSR - Terminate and Stay Resident.
Anything like G-Alarm/G-Profile, task managers etc. Any program that stays on or runs in the background I install to the phones memory. I think there is increased battery drain caused by accessing the storage card constantly IMO, so installing stuff like the above has made battery last 48hrs no problems. I too like to do a couple of full drain and recharge cycles a month .
I'm willing to bet that the majority of people who have battery issue probably has like a **** load of apps installed and/or unaware that some of their apps that they installed were running in the background. I've had the t8585 and the newer t9193 and never had any battery issue. The battery will easily last me 50hrs with light-to-moderate usage.
i can only confirm this.
after draining ur battery a couple of times, u need to fully charge it and it lasts longer than the first few days with the HD2
from new my battery life was totally useless. would barely last until 9pm no matter what i did.
two weeks ago my phone decided to forget it's pin lock number so had no choice but to hard reset the phone. since then i get a couple of days out of it and that's with heavy texting and web browsing.
i loved the phone before but battery life drove me up the wall but now i'm getting more life out of it i am now loving the device!
On the first couple of days I had the phone I had <40% by the end of the day but now even though I use my phone alot more I find I get to bedtime with ~50%
charging it unpowered after the drain also helps. (like with USB not the charger)
Most battery "manuals" state that completely draining the battery from time to time followed by full recharge is considered "good exercise" for the batt

Not to hijack the thread, just wondering if you're the talented skin designer that created some of the BEST for Wizbar? I still use them on all my HP PDA's
Few days ago i bought my HD2, and before that i saw problems about battery life on this forum.
When i bought it I drain the battery until he died, then i left him turned off and let him recharge over night (cca 8h). In the morning I turned him on and i used him all day max...and in the end of the day battery died at 23h, again, when he was off I let him chargeing over night (cca 8h). In the morning I turned him on and used him average, at evening, 23h, the battery was on 54%, I went to sleep and in the morning (after 7 hours) the battery was 52%.
2% in 7 hourse is very good...and 50% over day. I'm ok with that

All that does for Lithium-Ion batteries is to reset the "estimated remaining charge" circuit. It wont increase the available battery life it just makes the battery report more accurately as to its remaining charge.

energy rom's use a lot of power. i didnt knew that untill i flashed the Anastasia rom ( link ) battery life is great and it looks better than energy imo. and it easy runs 2 days for me
I've been very annoyed at the rapid battery loss with Dutty's series of excellent ROMs.
I started from scratch and didn't install any apps to the Storage Card just to be absolutely sure. I even put the phone into Flight Mode.
Tonight I finally nailed the culprit for the huge drain (we're talking 50% in a few hours): it was a 16GB "Memory2Go" SDHC card. With the card removed, I lost just a few percent over a couple of hours.
I also don't get the same drain with an 8GB Sandisk card installed.
Any ideas on how to get the 16GB card to play nicely?

cyanogen six sucks the battery life

My battery life on cyanogen six is down right awful. Every day I charge it at night and when I go to bed even if I don't use it its at 15%
Isn't there anything I can do?

I, as well, see about a 1%/hour drain when my phone is not in use.
Usually, unruly battery drain is due to a rouge application you have installed.
I'm getting better than ever battery life on CM6.
Try charging all the way, reboot into recovery, wipe battery stats, charge all the way again.

I did something similar... I got it to warning (15%) and then erased battery stats... I then ran my my phone until it died and died again... after that it shouldn't get past boot if so then proceed to boot it into bootloader. The bootloaders white screen should drain back up battery quickly so only leave it on for only 2-3 mins. Charge it fully powered off and enjoy 15+ hours uptime!
my battery sucks ass too it was never like this before??? kernel??? could a different kernel fix this issue..if so which is the best please be specific so many kernel to choose if any...please help..thanks!
does the phone radio matter because im using the 5.8.4 i believe..

cyan 6 has had terrible battery life for me. so i switched back to leofroyo latest beta rom and got back my 3hr/% standby battery life. with widgets and email checking every 30 minutes. i'm down to 2hr/% in standby. usually in a day i lose 25% battery life with mild internet use and calling. i charge my phone every two days. can't beat that.
Try manually closing all applications & services that are not vital to your phone, then test over a day or two. If that doesn't work, try a different kernel.
Okay I've had about enough of this. It goes down to 15% every day EVEN IF I DON'T USE IT AT ALL
Could someone recommend me the best battery life rom in town, even if it's the stock one?

This one is good. Best in town is hard to judge, but a lot of people enjoy the battery and stability:
http://forum.xda-developers.com/showthread.php?t=714184
Try blackbar v6.1 or stockbar v6.1. Those are the FRF91 build. I haven't tried the FRG33 but it's probably pretty great as well. The first post lists the changes from stock.
I'm fighting with battery life too, but problem is not when in standby where it uses less than 1% per hour, but actually using it (browsing) you can see battery lose 1% every two minutes... is it like that for you guys also? Really frustrating me...

Don't do this. Draining lithium ion batteries to completely dead is one off the worst things you can do to those batteries. It kills off their capacity
Charge to full, turn off phone and charge again until led turns green again, then boot into recovery and wipe battery stats.
15 hour uptime is average not excellent

This is an excellent ROM. i've used it until i switched over to LeoFroyo. They both use the stock kernel and in my opinion i think its th best.
i also like to downclock the processor down to 800mhz with setcpu. definitely helps with the battery drain while using the phone. Non of those 925mv kernels help out in my experience.
Well I run go chat and msn constantly, I use 40 percent display, wifi, 3g, sync, etc and its about double the length I got when it was stock. Right now at 12% and I'm at 16 hours and 32 minutes! I wipe battery stats every time I flash a new radio also it seems to help

This is way better battery life than what I get on Enom's, but I get consistantly 14hours to about 15% and I use my phone a LOT.
Really eh... Well il be sure to check out some new enoms! I'm feeling this nxsense too 13 hour first day not bad for porky sense

Heavy for me means more than 3 hours on the screen being on... as im constantly using my nexus... i just cant put the thing down for a min.. and yeap enom's rom with wildmonks kernel really helps the battery..

Extremly strange battery behaviour! Jumps Upp and down and drainage on stock Note 4

Note 4 unrooted, Stock 5.1.1
Fast charging enabled, great battery life untill about a week agoo.
All the sudden my battery have been acting strange. For starters it drains extremly fast! tried every damn app to see what is causing that! Cant find any thing. removed the battery and still dosent help
And just now i had 13% battery and 1 secound later it was down to 1% !!!!
I put in the fast charger and it says it cant charge, but charge icon is still there!
1 secound later its 3% and after that it jumps to 40% then gets back to 25%
Sounds like a bad battery bub. My first battery went Ro hell randomly like that and I found it literally was just that battery. I ordered a replacement plus little charging back up kit on amazon and that battery is normal.

Untill a week agoo i had as mentioned great battery life! But then battery began to drain pretty fast. but the battery jump is totally new and i got this today while looking at the screen.
Can even add that now after a restart i got from 25% down to 16% just after a restart and cache clear :S

That's pretty much how mine started. It was at random, seemingly had no reason to do it honestly. But the first instance it had i believe 15% battery left and suddenly shut itself off lol afterwards I just got another battery on top of an extended battery which I refused to use the fast charging function with. I've read too much and experienced first hand it just wrecks batteries.
strange mine start doing the exact same today. Jumping from 60 to 20 to zero in minutes. Any one advise where to get genuine replacement, not the ebay crap.
Thanks

I live in Sweden, found many Original batterys.. So i dont think that would be a problem. The cost on the other side, thats a nother story!
Hmm.. I suspect fast charging as well. This is the first phone i used with fast charging, and first time that this happens to me.. And i have owned many phones. :S
Will close fast charging, thow its a damn good function.

Same thing happened to mine as well. Ended up buying a two pack of Anker batteries on Amazon, and it's worked like a champ ever since.
I had some really poor battery issues after 5.1.1, also about a month after dropping my Note in water...anyways, I did a factory reset after having 5.1.1 for a few days, and now the battery is doing great!!! 10 -12 hours with medium to heavy use.
I have now changed to a new battery and dont use fast charge anymore.. but now im using wireless charging instead lol
Anyways im still unhappy with the battery, i will do a reset when i get time.
I went from 50 to 1 one night. This was on KK. I upgraded to 5.0.1 (BOF) three days ago and the battery life seems more stable and longer lasting. Try letting it drain until it powers itself off (at night) and charge it off until it is full. I have had to do this on other Android phones (an S3 was one) and it corrected strange battery performance, readings.

Note 4 Battery Problems

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.

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.

I had a similar problems, and I have received my new battery yesterday which has been charged in 51% so I drained it to 1%-0% without unexpected shutting downs, I have charged it again and so far it seems to be ok

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!!

Battery drain

Battery Drain
I have the Indian G6 with quad dac and its been 6 months since i own this and im facing huge battety drain. Earlier i used to get 5 hrs of SOT and now i barely reach the 3 hrs SOT mark. Even the charger got damaged and It lost the fast charging capability and charges slowly. I performed a factory reset but still its the same. I dont know what could be the reason but my charging habits were bad. I would charge the phone always at 0% or 5% and I would use the phone while charging but i followed this only since 2 months. I dont think this wouldve degraded the battery so quickly but i dont follow that anymore and charge the phone at 15% or 20% and uptill 90%. I still have warranty left and will they change the battery? Is anyone facing similar problem? Please help me sort out this issue because If nothing else works im considering selling this phone as soon as possible. Thank you.
If you go to Settings > Battery > what apps does it show that are causing your battery drain?
Battery usually has a 6mo warranty of I'm not mistaken

I used Samsung browser before and it drained 16% so I uninstalled that and I use Youtube Vanced which is using 14% now...but even without these apps I still see drainage. It was so bad earlier that I got only around 2.5 to 3hrs of SOT and after a factory reset saw around 4 hrs of SOT..but I have to charge the battery by late evening compared to previously where i would charge at night.
