After a full charge, unplugging causes it to drop battery %?

[BigMcGuire]

Unplugged for 1 hour - 6 mins of calls, about 20 texts. 84%. !!!!

I did that special charging where you plug/unplug. Almost all syncing is off and brightness at 10% manual. Grrr. I might just get the extended because I can't have it die this quick.

45% Display, 37% Voice Calls, 6% Cell Standby, 5% Phone Idle, 3% Android System. 2% Plugin Sample ????, 2% Market.
1 hour 30 mins unplugged, 81% battery now (haven't done anything really). Losing like 5% per 30 mins just on standby.

The extended seems like a nice option but that thing is HUGE! You'll need a backpack to carry your phone

The battery drain is a known issue with HTC. This is the same issue the Incredible had. The workaround that was recommended is as follows:

Plug the phone in and charge it until the indicator light turns green (usually around 4-5 hours), then unplug it wait a minute, plug it back up until the light turns green again (about one hour), unplug it again and replug it up and charge again until the light turns green. After this unplug you should have a completely full charge and not see the immediate drop.

Thank you!
Time to try it!

I also am not in a 4g area nor am I even close to one. I understand that the 4g network is a battery hog and if you are close to a 4g network your phone is searching for it in the background which helps to kill the battery.

I think that would explain why your battery life has been as unique as anyone else's so far. I live ten minutes outside of New York. the speed of the phone and 4G data rate is phenomenal, but the phone itself does not last until the end of the day battery life wise.

But I will try your bump method.

Most Lithium Ion battery managers require at least one complete charge discharge cycle for the battery manager to be accurate. This needs to be re-done anytime you change battery capacity.

This doesn't necessarily increase your battery capacity, but it makes the % remaining more accurate and enables battery management functions to run correctly.

Is there an app to toggle from 4g to 3g?

I have Widgetsoid... and theres a setting to toggle 2g/3g.... wonder if I can use that...

I've kept the phone at 100% (above 80%) for most of the last few days. I noticed that the battery % is jumping up and down while the mV doesn't move. I think I'll run it down and do a complete cycle and do the bump charge.

Well, at least discharging the phone won't present a problem!

I love my newest Godphone. There has been a few bugs suh as my wife sending texts not from her phone number, but from her simnumber. Of course the local store fixed it when the battery pull didn't work, and blamed it on a low battery. (40%, and they took it in the back. Dirty slappers.)

Anyhow, mine is only presenting a battery reading problem. After a full night charge, unplugging it will cause it to drop wihin seconds to 99, 98, then 97%. I cannot keep it within the 90s after just sending a text message.

Screen brightness is one step above dim, and the first thing I did was turn off sync, bluetooth, wifi, etc.

I'm more confused than anythig st this point. Losing ten percent in less than three minutes of unplugging is damn odd. Is anyone else experiencing similar problems?

What app are you using for battery indication? I noticed the exact same thing (97% when unplugged and 90% shorty after) but I get plenty of battery time overall.

I personally think this may be an app-related issue. I am using BatteryTime and had to choose EVO, since the TB is not yet available.

I'm using the HTC Battery Widget. I'm about to drop for the night, but before I do, this baby is hitting zero!

I've posted this before, but this is why you're seeing the immediate drop:

Your battery gauge is lying to you (and it's not such a bad thing) - xda-developers

Also, if you want to bump-charge, you should charge until the light turns green, pull the battery, put it back in, then plug the phone back in, wait until it's green again, then turn the phone on.

Tell it to the marketing folks. In 45 minutes I saw a 13% drop using the same setup I had with my Incredible, email running and checking every 10 minutes. I didn't use the phone for anything else. Last night my phone was going to shut off well before the end of the evening. Assuming the battery even had more charge, my phone wouldn't recognize it. Unfortunately the gage doesn't lie about a puny 1400mAh battery for a high powered device.

Update - An hour and 20 minutes after phone unplugged, battery drops to 73%. No usage, just K9 email running in the background. Something seriously wrong.

 

[slinky]

An hour and 40 minutes, now in the 60s. Looking at what is using the phone's power:

44% - Android OS
20% - Standby
2% - K9 email

Evidently there are problems somewhere here that have nothing to do with my email checking. I'll bring in the phone today to the store and let you guys know if something changes, trying to remain optimistic.

It could be email, it could be something else. Since actual processes aren't listed under Android OS, it will be tougher to identify the culprit, but it could be something interfacing with the OS causing the issue, it could be a sync problem of some sort, etc.

Download watchdog lite (unless you prefer another process monitor), use real time monitoring, and start uninstalling apps and turning off sync/data processes until Android OS stops using so much cpu time to find what's causing the problem.
