Why my Nexus S i9023 cannot be charged to 100%? - Nexus S Q&A, Help & Troubleshooting

As the title said, my phone was never charged to 100%, it is always 96% or 97% mostly. Anyone can tell me the reason?

They only charge to 96-98 for real. It is very unsafe to actually charge these batteries to 100% when it does chargd to 100% it usually drops to 98 when unplugged. 100% is more for looks.

You can also do it in CWM to wipe battery stats

Yah usually you have to condition the battery which us by draining till its zero then you charge to a hundred than wipe battery stats at 100%

Not Charging?

While I have my phone plugged into the wall it'll charge at idle. But if im playing zynga poker while it's plugged in, the battery will drain. Now while im playing I notice the battery gets pretty hot. Doesnt drain while im surfing the web or using xda developers app and such. Not sure why this is happening. The battery is only about a couple months old. Verizon gave me a new battery when I called in for a replacement phone.
Anyone have any ideas for this?

It could be because it is charging and useing an app that uses a lot of battery and functions of the phone. I really have no idea though. Just a thought.

Could be that, this is my 3rd droid charge. Not sure if my battery drained on the last ones

Phone is using more power than the wall is providing. Are you using the OEM charger?

I've noticed if I use very processor and data intensive apps while plugged it my phone will get a little warm

Charging current is controlled by the kernel. It's using more power than is allowed by the kernel. This is fairly common for me-especially when I'm hammering the LTE radio. When you want it to charge faster, leave it alone.

Alright good, atleast I know it isn't a problem now. Just making sure my phone isn't crapping out on me.
Thanks everyone

Yep, I think it's regulated at 800ma by kernel so it sounds like you have too much juice-sucking apps.
Your battery charges best if your phone is powered off.

Erratic Battery

My girlfriend is having serious issues with her Desire S. The battery can be full and yet it powers off. As you can hopefully see from the photo, the battery level spikes drastically.
Any suggestions?

Nexus 5 charging

The nexus 5's charge has a 5.0v output (correct me if im wrong) so here the question is it ok to charge it with a 5.3v output powerbank?
Sent from my Nexus 5 using xda app-developers app
Yes. Your phone regulates the current supplied to the battery so 5.3v will be fine.
You only risk damage of you go stupid voltages

Honestly, I'd personally play it safe and use the exact charging brick that the phone came with. Even in the Nexus 5 manual LG opposes of the use in using another charger other than the one the Nexus 5 comes with.

I used to use my wife's charger for he xperia z1s but I found that sometimes it would not charge even though it has the same specs so I would watch it and make sure it is charging correctly.

Original charger charging at half speed?

Recently my original charger only charges at 700ma vs the original 1200-1300 ma before. Now my phone charges half as fast, which is an annoyance but not a huge problem. Anyone got any ideas?

I had the same problem from day 1 when i received the phone. I contacted Google and they wanted me to send them the complete set of phone and box to send me a replacement. I simply used an older usb charger that came with my older phone.
I think its a quality or defect problem.

Just out of curiosity, how are you measuring the current draw?

Really? How do you see the "absolute" input current? I thought bmw only showed the difference between the charge and drain currents...

That is normal and avoids damaging the circuitry
