Battery has already lost capacity - Nexus 6P Q&A, Help & Troubleshooting

Hello everyone. I own my Nexus 6P for 6 months already and couple months ago i have noticed that my battery life became worse. for the first 3 months i could easily get 6 hours SOT on WiFi. Now with the same setup i barely get 5 hours. Phone is stock. In the beginning of January I switched mobile carrier (chatr to Fido) but it should be a big deal since they are owned by the same company and have same antennas. What might be the problem?

Same for me... 5 to 6h SoT 6 months ago, in the last month... About 4....and now after installing Elementalx kernel with Ex Kernel Manager (no tweaks) and the last Google update, I'm back to 5.5-6h SoT. Not sure what happened... Lol

Could be some app you've installed is not letting your phone doze or is otherwise chewing power. That's the dark side of being on the latest and greatest release of Android OS. We get to be the first ones to see issues with apps that don't work well on the newest release without some developer tuning.

Rouge app or process that doesn't play well with the current OS.
You might have a crappy battery but more likely something was installed and doesn't allow your phone to sleep.

Usually li-po battery deteriorates at a much more gradual pace than what you have described. Unless you have constantly charged and discharged your phone in the past 3 months up to 500 times, I doubt that your phone's battery actually lost capacity. Usually after 300-1000 (500 is the industry standard) cycles (total discharge to 0% and then total recharge to 100%), rechargeable lithium batteries start to fail its performance standard, which usually means 50% of the test batteries hold less than 80% of their initial capacity. With all that fancy numbers, I concur with the previous replies. Get BetterBatteryStats to see which app(s) have been draining your battery.

I should add that I've had my 6P since early January, and recharge it nightly. I do not notice any degradation in capacity from when it was new.

I've had mine since Nov. and charge nightly.
I top mine off whenever I'm in the car.

Brings up a good point. I wonder if it's best to keep the battery toped off near fully charged as much as possible? I know Apples stance with Macs say this but it has special conditioning circuitry built in.

Battery life after initial charges- your opinions

As we all know, the Galaxy S uses a Li-Po battery.
Having previous expirience with those batteries (R/C Helicopters), i know that they require 5-10 cycles of full drain-full charge to reach full capacity and start their normal life cycle.
Not too long ago, there was a thread complaining about battery life here, but i think it was due to people checking usage time on the first or second charge only.
In this thread, i'd like to hear your opinions about battery life, but please-
Only those who passed 5 FULL drain-charge cycles, reply. We need some objective information about it.
Personally-
I'm after my 4th charge, and already seeing HUGE improvement. When i recieved it i barely managed to go through a single day, and now i'm almost 2 days since i last charged it, played some games, browsed a little, made a few calls, and i'm still over 65%.
Waiting to do 2-3 more charges and reach optimal state to see what it's worth.
Mine is a Li-Ion and lasts about a day with almost constant use.

You are correct in that initially we were told the battery type would have been a Li-Pol.
However, since the phone's release it has now come to light that the battery is in fact a Li-Ion.
I made a post that mentions this here if you wish to have a read.
I’ve had my phone approx 2 weeks, so I’m on my 5 or 6th battery recharge. My phone has been on for 1 day 20hrs now. I’ve talked on the phone for about two hours and surfed for about ¾ of an hour. Wifi has been on all the time – Bluetooth about 3hrs. Current battery level is 70% - I must say after all the gloom and doom re the latest smartphones I’m more than happy with the battery life so far and does seem to be getting better all the time.
Wow this is too nice to read, I was starting to worry about my battery being wonky

In contrast I have had my phone since Thursday... I've charged it 4 times in 48 hours so far. I am using it a lot and am hoping I get thee performance rise soon.
Crabby
I'm pretty sure it will.
When i got my phone i charged it to full, and before the day ended i needed to chrage it again.
And now:
Last charge was thursday morning (GMT+2), and now, after 2 and a half days, i still have 40%.
I could probably go on for another full day.
My first few charges barely made it through the working day, but now the phone still has plenty of charge after 24hours. Although right now is an exception, as the lady is playing Abduction on it and will probably keep at it until the battery dies
She really should get her own Galaxy S. Although we're waiting on some GPS improvements before replacing her phone, she cant afford to get lost.

Correct.... She's far too busy keeping me in check, looking after our Granddaughter and the Farm.
I got my replacement SGS today (had to send the original one back as Carphone Warehouse messed up the order so had to send everything back just to get a new SIM) and been hammering it for 14 hours, literally 80% of that running games, using WiFi, bluetooth and GPS and I only got it down to 25% and hadn't even charged it to 100% before I couldn't wait any longer. If the battery does get better after the initial charge, I will have no problem with this phone.
Further to my earlier post...
Charged the phone to full before bed last night... All of the power widget functions of two exchange email accounts and hotmail updating every hour.
So with no other use for 8 hours the battery was at 91% when I woke up. Battery status confirmed that 57% had gone on standby and 29 % on idle
So... Presuming this bsttery use is constant when idle... My phone will be down to 70 % by 24 hours with no use?
Crabby
It varies greatly according to reception.
Good network coverage= less work for the transceiver inside the device=less power drain.
It's not really constant.
Turning off 3G other than when you need it helps as well.

Is this something you do as routine? I don't know if I have the patience to do that.
And my signal was 5 bar edge signal for my 'test'.
Since this morning, I watched 90 mins of video, surfed for 10 mins and made a 5 minutes voice call on the train... By the time I got to work, the battery was at 53%.
I don't feel my phone will last my journey home at 6 tonight, so I have had to put it on charge again.
But still... on 3 days old...

Battery life sucks - got a new battery

All
I have been suffering with poor battery life for many months now, I have tried all the obvious solutions, even going back to a fresh re flash with no other apps and still the same (i.e. barely a day with moderate usage).
Then it occurred to me that I used to get at least 2.0 or 1.5 days with moderate usage for the first 6 months.
I confirmed a while back my battery was no the bad batch.
Anyway finally I source a direct genuine replacement from Handtech for £10.
I swapped the battery (no other changes at all) and voila, I would say back to original expectation
Reflecting back, the battery charging and during use would get very warm (not a good sign) but there was no sign of battery swelling, etc...
With the new battery even after a long first charge the handset was completely cold.
interesting...
How long you used the original battery?
I know some Iphones that still last a day with single charge after 5 years of usage. So the battery still keeps the charge. My 3 year old Galaxy S2 still keeps the charge but not as good as new one. So at least Samsung batteries becomes weaker over the time significantly.

Original battery was barely 1 year old.
I don't overcharge and normally cycle it once every few months (complete discharge and charge).
I am now 20% down after 8 hrs, with the old battery it would probably be about 40% down.

[Q] Is the battery gone or miscalibrated?

hello everyone, I'm a new note owner, I bought it used and I think it has two years on it, but it is in great shape. I noticed however, that the battery life isn't that amazing as people have told me, this coming from a Galaxy alpha user. I will leave screenshots of today's battery life and I think it isn't that amazing what it got
I've heard about battery miscalibration, is this really a thing? I can try and calibrated but I need to root it, & I wasn't really looking forward to reading it, since its lollipop on stock rom.
The screenshots are bellow of screen on time and total time, you can see that it's not consistent and I charge my phone two times a day.
http://imgur.com/a/ShaLI
I'm using lollipop official rom flashed on Odin via download mode, yes the rom is compatible with my country's frequencies so there's not really a problem there.
I notice however that the battery sort of goes down faster sometimes more than others, sometimes even going as far as draining 10% simply being on stand-by with LTE enabled for 2 hours in my pocket when I'm in class.
Is this normal behavior?
I don't think there is any such thing called miscalibration, I mean I am not sure, but well.
If your phone is 2 years old, then I think the battery has seen its life, time to get a new one mate.
Battery recalibrates itself .
However as the battery is old then Drain the battery to 5% power off charge fully unplug wait one hour top up charge and use .
Next step is new battery Anker brand is good .
Wiping battery stats/ supposed calibration has nothing to do with battery calibration and will make no difference .
Lithium-ion batteries last about 300-500 charging cycles, after that the risk of it dying increases exponentially. Some last 5 years, some 1. It depends on usage and environmental factors.
There is no such thing as recalibrating a modern lithium ion battery. It doesn't have a memory.
New battery costs about 20 quid, it should solve the problem.
Also, did you do a reset after the update? Updates can cause battery drain too, quite often.

No, I did not do a reset after the update. But I noticed this before updating to lollipop, I had to do some running around before I got home the day I bought it, and it was running KitKat 4.4. I got it with 93% of battery, walked home for a bit and was down to 65, went to the shopping and back, got home with 40 to 35%. (I bought the phone at around 5 pm and finally got home after going to the mall at around 8pm)

First of all do cash reset/factory reset and then check your battery life. Probably your phone overloaded with old garbage/soft etc...
Not really possible for battery to be degraded after 6months of usage, unless you charged from 0-100 3-4 times a day lol

i dont think the battery did degarded... but i just dont get how people said they can havae like 6 hours of sot... so just wanna do a change before the warranty goes out.
i dont even use 25% of my 6p per day since I use my nexus 5 indoor and 6p outdoor.
btw, do u know the charge cycle for the 6p? and how was the quality of huawei battery?
Got my phone in November and charge it once a day since.
Stock not rooted.
Noticed recently phone battery has been winding down much quicker than prior.
Say within last 2 weeks.
Anything unusual happen out there in update land?

Are you frequently in areas with bad cellular signal? That will make the radio transmit at maximum power all the time, draining your battery.

No - not really.
Not Band 12 on most days - Band 4 for LTE data.
The only difference is I setup for the first time a Tasker profile to turn on Waze when I plug into the my car & it activates the Bluetooth and then Waze.
I make it a habit to turn off the High Accuracy GPS manually after disconnection.
It's my first Tasker activity ever so not sure if it's doing something in the background I am unaware of.
One thing I noticed that made a big difference, is to clear cash after every update, I don't use phone much, but I can average 5+ SOT hours, per cycle, never went below 20%. Some times my phone goes for 3 days with 2 or so SOT before it reach the 20%.

Battery drainers:
Brightness (outside)
Heat (outside/brightness)
Usage pattern
Signal coverage
Bad update
Play store
Erroneous apps
Battery life obsession (personal one of mine)
Bad battery (build quality)
These are all factors that can cause quick draining of the battery.

Just popped in a new Cameron sino battery from eBay. 25.00. Wasn't bad camera glass is tedious but not impossible. You can always get another one and pop it in if you do break it. No more shut offs. And yes the batteries in these phones are bad but I was still able to use it, just couldn't let it get below about 25% or it's possible that it would just shut right down. But now that is over with for 25.00. these are still very good phones if you are willing to do a little work.

How is your battery after 1-2 years?

Hi all,
i own my OPO since january 2015 and started noticing that the battery doesn t last like it used to be. i now usually get 3 hours of screen-on and it seems that the battery even takes longer to charge. How is your opo battery doing after more than 1 year of service? i'm asking because i want to know if it's a software problem that drains the battery (latest cm13 nightly) or really the battery got degraded
almost one and a half year old and the battery is still good.
after 2yrs, my batter gone down from 10hrs to 5hrs
What karthics4 said!Need a replacement soon!
Sent from my A0001 using Tapatalk
if it got really degraded, change it.
Before replacing it, what should i check to be 100% sure that there is no battery drain on the software side?
With the right ROM and kernel I have much better battery life than two years before.
Oneplus One
I'm having less battery time than when it was new.
I have 3h SOT max currently.
Me 2. Currently looking for a good battery replacement...
After 2 years the battery is still extremely good.
Still lasting a day with ressurection remix and governor set to smartmax with lte,only wifi if i charge it to full it will consume only 35 to 40%.
I've had my OPO for over a year and battery life is excellent on Omnirom Nightlies (screenshots attached)
I get about 5 or less hrs SOT on CM13 Nightlies but with a custom kernel like Boeffla I can UC CPU and GPU and get about 6 hrs.
When I had my phone new on 4.4.4 KK I used to get 6 hrs SOT on COS with no tweaks whatsoever over 2 or more days.
Of course it will less, but I'm still getting 4-5 sot. I bought mine since the invite was sold like 40 dollars lol.
remmember that lithium batteries degrade when heated... and they get hot (40 C).
another thing to remmember is that android 4.4.4 that the OPO was delivered to us lasted more that MM and Lollipop...
after two years my battery is good, not bad not awesome like it new, but good.
I'm using ressurection remix with undervolt -130 MV
And I still can go to university and home with 50% battery.
The problem is you'll not find any ORIGINAL replacement battery for that phone. Its all label-faked batteries which will not last as long as a 2 years old original one...
I tried already some of them..
in GPS, choose the "DEVICE ONLY" mode and see that the battery will last more. CM bug...
Hardly any of the replies in this thread are useful. Most of you started out with KK and then went to LP and MM, which have much worse battery life than kitkat, so you don't know how much of the degradation is from battery wear. Flivercod's new AICP MM rom is the only one I have seen since kitkat that has a similar battery usage profile to kitkat - the screen uses at least 4 times more power than system, play services, OS, etc, so to me only someone who was running this rom could make a valid comparison to how their battery life was now vs how it was new. For me, I have dropped about an hour of SOT, from 6 to 5 due to battery wear, which is about what you would expect. Due to this, I would like to replace my battery.
It peeves me to no end, like Guido83 said,. that you cannot find an OEM battery for the OPO. They all appear to be counterfeit crap from reading the reviews. Oneplus does not answer emails asking how to purchase an OEM battery for the OPO. So, I guess you are SOL when your battery gets wonky or just old. With phones now being fast enough and good enough to be used for more than 2 years, except for the frigging battery, I am waiting until some manufacturer decides to make one with an easily replaceable battery (and that has good support on XDA) before I purchase another. Until then it's the OPO and my backup Note 4 (which I rarely use since it has awful GPS despite having a replaceable battery and SD card.)
15mths in and my battery life has improved dramatically just by switching to RR. If you're rooted then it's worth trying out another Rom.
Third time lucky for me. Oxygen was by far the worst for me. I couldnt even get to 4pm without a charge up. Since installing RR I'm finding battery life has more than doubled.

One.five year old with max Sot of 4 hrs
