,this is how i calibrate my battery,before i have 45min of standby it will decrease from 100% to 99% but now it is 2hours & 34min with minor texting before it go from 100% to 99%,i felt the drain after 2 weeks of overusing my phone (1week playing paladog and 1 week flashing different roms,kernels and theming my phone with different launchers),
- Charge your phone to 100% while it’s on.
- Unplug it from the charger, power off, then charge for 15 minutes with it in a powered off state.
- Unplug charger from phone. Power it on, and then charge 15 minutes while the phone is on.
- Calibrate battery using battery calibration by NéMa then unplug charger reboot.
- Power on, charge for 15 minutes then unplug.
- Finished.
note: deleting battery stats(calibrating) don't increase your batterylife said by others and it is just a placeboo and i believe in them,but it fix my battery drain so why don't we give it a try,there is nothing to lose,battery drain is so annoying.
,thanks to NéMa for the awesome apps,
,thanks to jgezau for his thread as my reference,
,please hit thanks if this helps,

Is the first charge on the Nexus 5 still as important as a few years ago? Or is the N5's Li-Ion battery not as sensitive as Li-Po batteries?
I always used to plug in a new before booting them up, charge the battery completely and then unplug it. When the charge went down to about 5%, I plugged it back in. I always did that two or three times and then - while still trying to do it like that all the time - allowed myself to charge the device for a few minutes only when it was necessary instead of plugging it in and leaving it at home.
Well, on the N5, I didn't manage that - I actually forgot to monitor the battery level yesterday evening before going to bed. This morning, I noticed that the battery had reached 1% during the night and the N5 shut itself down.
Of course, I did now plug it back in, but I wonder if I could have damaged the battery by letting it run down to 1% on the first charging cycle? Or doesn't this matter at all and it will still reach its full capacity after a few charging cycles?
Thanks

I wouldn't worry about it, running a battery to empty is indeed bad but they don't allow you to run it to empty. It is programmed to show 1% and shut down before the battery itself is at 1% to prevent you from damaging it.
Use your phone, when charge is about 20% connect your charger and do not disconect until reaches the 100%.
This is what i have done with mine.
I have reached 2 days standby with about 3 hrs of screen on time.
I have noticed that when i plug my Z5 in to charge overnight, it will charge to full in just a few hours and then remain plugged in for the next ~6 hours until i unplug the phone 'fully charged" in the morning.
My theory is that the phone loses charge (maybe to protect the battery?) when left plugged in at full charge.
I will only get 3 hours SOT max if i leave my phone charging overnight. But if i unplug my Z5 as soon as it is fully charged i get 5 + hours SOT.
Also, often when i plug my phone into charge at 1 or 2 %, it sometimes actually causes my battery to die, before the phone boots again and starts to charge. Does anyone else notice this?
I am using the stock sony UCH 20 charger with came with my Z5.
What do you guys think?
That does sound peculiar. It should be noted that while it is normal for the phone to protect the battery by cycling between 90% and 100% when plugged in (battery gauge doesn't account for this, that's why it appears full all the time), it definitely shouldn't cause a 40% difference in SOT even if you happened to unplug when the battery is at 90 percent.
Yes, you're right. Once the battery is charged to 100%, the phone stops charging and will let the battery drop to around 92% and once it hits 92% it will start charging again to 100%. Even if you unplug the phone when it's showing 100% after charging at night, it might actually be charged to 93% for example. That's why very often people complain that the first 10% of the battery drops very quickly, while in fact it's just the battery meter catching up with the battery charge. This is done to protect the battery and ensure it retains charge after many cycles.
Regardless of that, the difference should not be that huge. For me it's usually extra 30 minutes SOT.
It seems the stock firmware has a load of random wakelocks but I have hope that a soon to come update will fix most of the issues, if you are rooted I suggest that you use greenify or amplify (reqires xposed)

Sounds like a software problem, try the following solutions:
If you have root, try this method
Discharge your phone fully until it turns itself off.
2. Turn it on and let it turn off again.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Unplug your charger.
5. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on the screen as well.
6. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
7. You want to repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without being plugged in.
8. Now, install the Battery Calibration app and, before you launch it, make sure your battery is at 100 percent again, then restart.
9. Immediately launch the app and recalibrate your battery.
10. Once you've calibrated your battery, discharge it all the way down to 0 percent and let your phone turn off again.
11. Fully charge the battery one more time without interruption while it's switched off, and the Android system's battery percentage will be reset.
If you DO NOT have root, try this method
1. Discharge your phone fully until it turns itself off.
2. Turn it on again and let it turn itself off.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.

8. Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.

Guys, how do you calibrate the battery after flashing a ROM ?
After frequently flashing some custom ROMs, now on a rom, the fone gets switched off at around 16-18% and when switch on just after plugging the charger the battery shows 35% charge. This happens even after some repeated fully draining battery and then fully recharging back to 100%.

I don't know if it'll work with the custom ROM but it had worked for my non rooted moto G. It's worth a try though.
1. Turn your phone on and charge it for 8 hours or more.
2. Unplug the charger.
3. Turn your phone off and charge it for one hour.
4. Unplug the charger.
5. Turn on the phone and wait 2 minutes.
6. Turn your phone off and charge it for one hour.
7. Unplug, turn it on and use as normal.
Your battery must be calibrated by now.
Hope it helps.
I just had a new battery installed in my Pixel by Ubreakifix because my battery had been draining quickly. My problem is that the battery continues to drain quickly even with the new battery. My understanding is that they install OEM batteries so I don't think that the new battery is the problem.
So, I tried to calibrate the new battery using these steps found here:
1. Discharge your phone fully until it turns itself off.
2. Turn it on again and let it turn itself off.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Unplug your charger.
5. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on-screen as well.
6. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
7. Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
8. Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
9. Fully charge the battery one more time without interruption and you should have reset the Android system's battery percentage.
I seemed to get caught in an endless loop on step 6. After charging the phone to 100% on step 5, I would disconnect the charger and restart the phone. Every time the battery percentage would drop to 60 or 70 percent after restart. After doing that about 5 or 6 times, I gave up on that step because it didn't seem to be making any difference. One cycle of doing this tends to take several hours because of the charge time from 60 percent to 100%. So, this ended up being a many hour process. Should I have just kept repeating step 6 over multiple days in the hopes that eventually after many charge/restart cycles it would eventually register 100%?
Now the battery calibration seems completely out of whack. I have fast battery drain and the pixel shuts off sometimes around 30 or 20 percent remaining battery. Now with minimal screen on time, the battery might last 8 hours. It used to easily last all day even with moderate screen on time.
Any help would be much appreciated!
I would take it back to Ubreakifix. Tell them the battery drops from 100 to 60-70 after a restart. It sounds exactly like what you would expect from a bad battery.

Yep did that already. They replaced the battery again (for free) and still the same problem. The technician said that this has been a common problem for many pixels after they’ve replaced the battery. He claims it’s because the pixel can’t handle android 10 but I don’t believe that.
I recently bought used Pixel and Pixel XL.
The XL exhibited the exact problems you mentioned (looping steps 5 and 6 and shut off at around 20% mark). Even have this on camera (btw, split screen opening some games like PUBG with your battery status on the other side is a good way to drain the battery and show battery percentage). Not sure if the battery was previously changed but I took it back to the seller and got a refund.
On the other hand, the Pixel (non-XL) is running on Android 10 just fine. Did the battery calibration as you mentioned and it was good to go.
