Battery life sucks?!

So last night was NYE. I took my phone out with me and the battery was at 100% according to Touch IT ROM.
I took 4 or 5 pictures which were terrible, the camera sucks.
I stayed at a mates and woke up this morning, the battery was down to 20%?!
I haven't even used the phone and after 16hours or so the battery was nearly dead. What the hell, am I doing something wrong.
I always thought the battery sucked but this is a joke

same here ill try to get a new one

Check if you have any applications running in the background. Do you have Wifi turned on, bluetooth? Every module that is enabled keeps sucking power. If you don't turn them off, your phone can indeed get drained pretty quick. The battery is just fine, 1500mAh isn't bad at all. Do keep in mind that - due to the big screen and many options - phones like this just don't last for a week.
Also, did you fully uncharge your battery when you first used the phone?
If the problem persists, you can always contact SE to get a new one, as it's not supposed to drain that fast.

I know on the old P990 if you didn't exit the camera app correctly it just ran in the background and drained the battery. I do a double check in the task manager every so often to ensure that nothing was left running that shouldn't be.

This is a thread from Touch HD about AE Button Plus.
I am testing this now on my X1 because I am alos not happy with MY battery life.
dingolino

the camera is not that bad, actually it's one of the bests I seen in a mobile device... anyways, don't expect to take, for example, good night photos, but actually, with good lighting the photos came really nice.
as for battery; I'm sure you shoudl have something (maybe wayfinder) running in the background, with moderate use I get 3-4 days of battery without problems; and I never let it get down 40%.

i get about 2 days max on my battery. thats with nothing running in the background, althought it does ckeck my emails every 15 mins.
shame u cant buy a bigger battery like a 3000 that would last twice as long as 4 days on one charge would be amazing

Hm.... i have another one for you guys. I was using the phone non stop for the past couple of days. Wi-fi is always on and i watch media and use opera a lot. The battery lasts for about 8 hours. When i got the phone the battery was almost dead. I did charge it but for a couple of hours only. Then i charged it overnight for 12 hours. Did the fact that i did not charge it for a long time from the box affects my battery life???

yeah, i did that with a phone i bought about 2 years ago and had to get a new battery as the original one would die after a day or 2 (should last about a week as was standard phone). i always leave a new phone on charge overnight now so i know its charged all the cells

I'm not going to say that you guys are wrong, but...
This phone, does not need to be fully drained the first time you use it, nor does it need to be fully charged. That was only an issue on older batteries, it's not an issue anymore.
I also believe it says so in the manual somewhere So, I'm guessing you guys had some defect batteries, cuz it's not an issue with the battery thats in the X1.

are you using Itjes latest HD based rom?
I found I got really bad battery life out of it for a couple of days till I let it run down to under 10% then charged it again. It's working fine now.

I heard the same thing from a couple of people. Older batteries had that problem but modern ones don't. I just wanted to make sure =P

u might be right. like i said it was about 2 years ago it happened to my phone. but why take the risk

The only thing I had on was wifi and check mail every 30minutes.
I only use general useage (8 pictures and a few messages)
but that was it. I dont understand. I charged it for 20mins and its gone from 20% to 60%.
7hours later its only on 50%. Strange thing is, my phone has been on a radiator all day and it hasnt last that much charge.
Last night it was freezing -4c outside and wasnt that warm inside, then I slept in a cold room. I wonder if heat has anything to do with it :S

Did you flash your phone recently? was the battery at full before you flashed it? it's been reported as a problem on other phones (I remember the UNI used to do this) that if you flashed when the battery wasn't at full it messed up the power levels.

Mine was crap the first few days. I read somewhere on this forum to run battery to zero and charge overnight with the phone off. Mine now lasts all day and is recharged each night.

Just a sidetrack with regards to batteries...
When I charge my X1 with the device turned on, the battery tends to heat up till even the casing is hot to the touch. Is anyone else encountering the same thing?
However, when the device is off while charging, the battery doesn't heat up.
Weird...

It depends on what applications you've installed.... Touch flo drains it like hell.
My phone looks like this.
I use SE panel 1, no other gimmicks.
Pocket player for music 2 hrs each day.
15 min of video here and there.
2 hrs of phone calls, and a hell a lot of messages, which means keeping on switching the phone from potrait to landscape and so on...
SPB phone suite.
SPB wallet.
SPB Wireless manager.
I get a solid 2 days with about 15% remaining at the end of the second day...

As much as possible put the phone in sleep mode when you charge the battery. And the battery gets more heated up when charging over USB.

Hi!
I had the same problem some days ago. Even if the X1 slept on my desk with no application running, after 2 days the battery was empty.
I thought about what I installed last and deinstalled Batti. And now the battery lives much longer.
Btw... does anyone know a good app to show the status of the battery? Or how I can show it instead of the clock?
Batti was great but charging every second day was not.

Dood, Its a bit ridiculous.

Ok, I have read literally countless threads about the less than desirable battery life of the G1. However, no situations quite like this.
I bought my Dev G1 used (used for 3 weeks, supposedly). I was noticing that the battery was lasting like two hours, of course I was using it, and it was downloading some large updates.
However, Last night I went to bed about 11:30, and my phone was at 100%. I put the phone on standby, (because I didn't want to charge it all night on a full battery). I woke up @ 6am, and the phone was completely dead. I will stay on for about 30 sec and then shut off.
Thats a bit ridiculous! 6 hours on standby???
I left the phone off, and I am now charging it, in an attempt to "Condition" the battery, but Im not convinced that the battery isnt bad.
Any Opinions/comments?
**EDIT: Oh yea, I forgot to tell you. "Use only 2g networks" is checked, and GPS and Wi-Fi is off.

1. did you check that it's an original battery and not some no-name?
2. as you said, try to condition it for ~2 days, always let it run dead, try to switch it on again once or twice, keep it off and charge it 2 more hours after the led is green. repeat this four, five times, if nothing changes, call t-mobile and complain. they might send you a new one.

Sounds odd for sure. If I leave my fully charged dev phone on standby (and 3G no less) overnight it's never below 80% when I wake up 6-9 hours later. Usually 85-87%.

Its not a no-name battery. I am an AT&T customer. I hope that conditioning it helps.

sorry, didn't pay attention

Its all good. Im just really frustrated. My Tilt lasted me two days of moderate use. I honestly need at least 6-7 hours of moderate use out of this phone, or Ill be forced to sell it.

I got 28 hours of moderate use out of my phone yesterday and it was only down to 20% at that point. You said you take it off the charger once it's full? You should leave it plugged in for a while longer.

Yea, see I left it plugged in pretty much all day yesterday. I was tethering with it, and the USB charges while tethering, Correct? So when I took it off it was fully charged.

don't charge it via usb, ac/dc seems to work better.
don't know why but many people say so..

Update: I plugged it in to my wall charger @ 8:00 am this morning. I just got a green LED. Ill leave it plugged up until about 1:30pm, and post the results later tonight. I hope I can see some difference...
By the way, I notice also that when its plugged into the USB, it gets VERY HOT around the battery compartment

Yes it does get very hot. Tell us what happens when you unplug it later. I noticed this with one of my old Window's Mobile devices, the battery lived less than 15 seconds.

Have you tried using the "Watts" program to measure battery stats.
Maybe you can post a screenshot after leaving it in standby for about 3-4 hours.

Never let a lithium-ion battery run until it is dead!!!!!! They aren't like NICADs, they have no memory effect, and this will damage them. See "Lithium-ion Battery" - Wikipedia

On my ATT Tilt I had 2 extra batteries and could barely make it thru a 10 hour shift at work with all three. Now with my G1, I have the same 2 spare batteries, and still barely make it thru a 10 hour shift on all 3. So, lifetime seems the same to me. They both suck batteries.
Shaggy

Well, After charging the battery yesterday afternoon, I used it heavily for about 9 hours. I used it way more than I would under normal circumstances. That was just after 1 cycle. It finally died about 10:00 and I left it off and charged it over night (about 7 hours). I will see if it lasts through one full day of normal use.
Im a little concerned about what Bill said. I certainly dont want to hurt the battery. This is the first I had even ever heard of this being potentially damaging.

i meant let the phone run dead, not the battery..
ninjaedit:
clarifying it further: use the phone until it shuts down, switch it on again, wait until it's off, switch it on, wait until it's off and then charge it using the wall charger.

What Bill said is true but conditioning the battery once a month or so is not as destructive as it sounds.
Just try not to do it all the time and it won't kill your battery.

All I know, is that it helped tremendously after just one time. it went from 6 hours in standby to 9 hours of heavy use

i took my ADP off the charger at 6am today...n nw its 1am...power manager show battery level at 29..n i used it to click a few pix today...listen to some music for about 2hours..so all in all i am pretty satisfied with what i have got..but some(some means like maybe once in a week or something) days the battery doesn't even last 4-5 hours..even when its on standby..i simply don't understand why this happens...!!!!

Phone shut off at 32% and only charged 7% in 1h30m with fast charge

I work 8 hour shifts and my 6P on Pure Nexus lasts through the shift with ~30% when I get home.
I was listening to music through Bluetooth and when I turned off my headset around 5 hours into my shift, my phone shut off and wouldn't turn on. I was in and out of the freezer, so I thought it was the cold. I got home, turned it on and plugged it in and saw it had 32% left.
An 1h30m of charging and it only charged 7% which is really unusual and is the first time.
I have AccuBattery Pro and it is saying it's going to take 10 more hours to fully charge using fast charge. Android lockscreen says "Charging rapidly. 12 hours until full."
Also in AccuBattery, although my design capacity for the battery is 3450 mah, it normally says estimated capacity is 2200, but is now saying I have over 5000 mah in capacity.
When unplugged, it has a screen on discharge rate of 50-70%/h when the average is 23%/h.
Is the battery dying? I thought it would gradually decrease in capacity and not suddenly change overnight.

When my battery bug hit..it just hit. No warning signs or anything. I was crapping out anywhere from 60%-10% and everywhere in between. I bit the bullet and RMAed for a new battery (they gave me a new screen too for whatever reason) Before i sent it in my Accubattery stats were saying i was at 75% capacity and now ive been at 100% capacity since i got it back and i can happily go from 100%-0% like its supposed to.
Although your situation does sound unique its almost certain you'll need a battery replacement.. or try a new ROM and see if it keeps happening.

Unfortunately, I got my phone from Rogers around November 2015. I don't even know what they can do about it. It's been averaging about 14%/h charging which is about 1/3 the speed. I've been using the same ROM for several weeks with no issues and haven't installed anything new lately other than app updates. I can try upgrading Pure Nexus, but it seems like they have a power menu bug at the moment.

Do you think your charger could be broken?

My wife has a 6P also. I was trying her charger and it's the same thing. I've rebooted twice. It's still draining at least about twice the normal average when disconnected.
So it's roughly draining at about twice the normal speed without doing anything and charging at a third the normal speed.
I seriously can't afford to replace it. I regret choosing a phone without replaceable batteries and will not do that again, which means no Pixel phones. At least I still have my Galaxy Note 3 which still works.

if i were you id backup the entire phone (or whatever is importannt to you) to my computer and download the J factory image and do a fresh clean flash and pray that it clears out whatever is going on. Sucks to start fresh, but worth a shot

I use FolderSync to backup my phone nightly to my NAS server.
The slow charging speed may be due to high cpu temperature. It was hovering around 40° for whatever reason. I set it down on a cold granite window sill and the temperature dropped to 35° and was charging at twice the speed, but still slower (1000mah vs 1550mah from before). I've been holding it for a while and the temperature is again going back up with charge speed slowing. Again, I've never had this happen before.
Thanks again, I'll probably restore the phone and bring it to Rogers later this week to see what they say.

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.

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!!

Sudden shutdown 30%

Ok so my phone is the 2017u, running currently the latest LOS16 but this shutdown has happened on 15.1 unnoficials and official.
Is this battery crapping out on me finally as when I was using my accubattery it reported around 72%.
I have a replacement Cameron Sino to fit but since that in itself could be over a year old (new at least) I don't hold out much hope it's not down to 90% just through age.
Cheers

72% should be decent, although not great. Calibrate your battery.
Calibration:
Drain to 0%, boot phone drain to 0% again.
Charge to 100% without booting if possible. Otherwise charge while in TWRP.
Unplug
Boot phone, then charge to 100%, unplug, reboot, charge again to 100%, repeat until you have 100% after a reboot while unplugged.
Drain to 0% without charging.
Boot phone and charge to 100% while booted.
Then reset Accubattery, do two cycles from 100% to 0% then charging to 100% while booted, no partial charging. Then run normal usage for a week, see if it reports anything different. If your capacity is around 2000mah, you might want to consider replacing it.

Cheers and have done that cycle before for calibration. Does flashing ROMs throw out the calibration as generally always seem to bugger up my phone every couple weeks flashing something that breaks it or doesn't work.
Will do it when I refit my new battery. I happy to burn this battery out this side of Xmas as wanting it to donor its board for a battery mod I have planned anyways.
Was just wondering if it's likely to be that my battery is fooked that's all. It seems to shutdown to dfu mode and then when plugged in it automatically reboots and shows 30%.

If your phone is going into dfu and the battery issue is occurring afterwards. It might not be the battery. It wouldn't hurt to get on a more stable ROM that doesn't dfu, do the calibration again and retest with Accubattery.

I think LOS16 is stable enough. It seems to be at least.
If the battery is below 50 % then it sometimes dfu's if I ask to much of it when the ambient temperature is cold so the actual phone is cold to touch or if I feel heat of the phone around 10 o'clock of fingerprint scanner.
Typical example of cold shutdown is could be speaking to wife on WhatsApp back in Canada and boom it's gone and won't reboot until I plug it in.
Sometimes when Ive tried to use the camera or do moving files and it's warm wherever I am it will shutdown also.

Well you're not the only one who has reported dfus with the latest Los16 builds. So as I said, you may want to make sure it isn't the ROM first. Try testing your battery out on DotOS 2.5, just to be sure, as there haven't been any dfus reported there. I know this would mean clean flashing and starting fresh for a few days, but you can restore your LOS backup as soon as you find that you still have the battery issue with DotOS.
Honestly though, from your latest description, it sounds to be the battery.
Are you using another kernel, like Schwifty?

I've played about with schwifty 4, 5.4, 5.5, 5.8 and 5.10 but reverted back to LOS 16 kernal for now. When the next stable schwifty comes out I might flash that though I'm feeling again this side of Xmas it's not a problem.
My biggest problem is I am moving back to Toronto next year before the spring and I can't be having my phone dfu'in on me if it's too cold hence my asking now to try to work out whether it's the battery or not.
Is there anything I can run after a shutdown to report stuff like a logcat or something ??
Edit
Also it takes an hour to charge my phone to 100% from about 87% which makes me feel the battery is just done now. Remember the same happening on my old nexus 6p and nexus 5 before that.
And if it does get up to 100 it drops charge quite quickly until about 80% then it seems to normalise after into a reasonable rate of loss depending what I'm doing etc.
The phone in TWRP only charged to 94% and had been there for 20 minutes, basically the time it took for my breakfast to come and to be consumed at my local wetherspoons (Brit reference)

Oh wow, yeah, all indicators of a bad battery. I wish i could recommend a good seller, but the one i bought one from gave me a battery with only 80% health. I got 50% refund back, since they didn't want to do an exchange. Still haven't decided if it's worth getting another one. I'm pretty content with 6 hours sot.

Wish I could get 6hours sot. It's ok. I hope my Cameron Sino for the grand x4 or whatever it is will be fine. I am going to hack my back out soon and use my dead battery board to solder in 2 replacement 3000mah or whatever fits batteries.
My Cameron Sino wasn't expensive and brand new so I hope it's in good shape. Either way 2 new lipos from eBay and a small Dremel will do the job haha

Replaced my battery this week with a Cameron sino new from eBay here in the UK. Massive difference to battery life and now the phone is lasting more akin to what I expect from an 820 powered phone.
I'm running
09/18 los16
Schwifty v5 stable
Gms magisk.
Had a nice flat line last night when I was in bed.

Ok so my phone is the 2017u, running currently the latest LOS16 but this shutdown has happened on 15.1 unnoficials and official.
Is this battery crapping out on me finally as when I was using my accubattery it reported around 72%.
I have a replacement Cameron Sino to fit but since that in itself could be over a year old (new at least) I don't hold out much hope it's not down to 90% just through age.
Cheers

i have same problems here so now and then,also happens on older roms.
also weird battery drains and accu % on statusbar.
Some people claimed my battery is downgraded etc,but at this point i think its caused due the burn in display stuff (when your phone is hot and decide to change roms)
i think replacing your battery doesnt solve it
