[Q] Note 2 new battery won't power on without power cable

[kevingt01]

When I swap the battery in my note 2, it won't power on until I plug it in for a minute even if the battery is charged. Any ideas?

Edit: some more info: I was having bad battery drain on CM10, installed battery doctor. I thought I'd try a new battery as well for the battery drain and started noticing that it wouldn't power on after changing the battery. I formatted, refreshed and installed slimrom 4.3. It looks like I'm getting better battery life, but I have basically nothing installed. I'm still not able to replace the battery without a power cable to "jump start" it. Its almost like the phone doesn't even detect the battery until I plug in a cable.

Update: I don't have any better battery life with slimrom. I'm loosing about 8-9% an hour in standby. About 5% an hour with the phone powered completely off. I have 3 different batteries that all hold charge when out of the phone.

Are you using one of those crappy GOLD Chinese batteries? That might be your problem, don't know why, or of all of them cause issues, but a co-worker bought one for his HTC and was having a lot of issues.

For the battery drain you should at least try to diagnose what is causing it. Either install Wake Lock Detector (free on Google Play) or Better battery Stats (paid on Google Play, free on xda).

Most of my battery drain are constant and numerous wake locks caused by Goolge apps, including Keep and Google +. Once you know what is causing it, it will be easier to fix.

Update for anyone with similar issue..

I followed a guide on here to get back to factory stock (no root, stock recovery, etc). I had problems getting into download mode at one point and thought I was completely bricked until I decide to try booting without the battery even in the phone (powered just by USB). I was able to get into download mode that way and revert to stock.

Here's the strangest part to me: battery life is now back to normal. Not just regular use and standby, but completely powered off, I now only loose 0.5-1% an hour where I was loosing ~7% when powered off.

I don't know if it makes a difference, but I've also been keeping my wifi off. I'm experiencing terribly weak wifi transmission (still trying to figure that one out) that will cause my phone to loose wifi connection, or it will stay connected but is unable to load anything. Maybe my wifi issues relate to the crazy battery problems. Who knows.

Hi I have the same issue on my Galaxy Note 3 N9005. Battery drain when phone completely off. Can't turn on after swapping battery without charge. Tried factory reset, flash stock rom issue still exists. Any suggestions? Thanks.
