[Battery] Fixes and Tips

And it's not just the trickle charger taking a long time to finish charging the last 10%. Even if you leave the phone charging for hours after the light turns green (when still not shut down), if you shut it down it takes another 20 mins to get to green again.

Mines the same to. Shouldn't this be reported to VZ or HTC.

Probably, it seems a simple patch could fix this. But they are such big companies who think they've already tested the shit out of this phone. Why would they listen to one person?
 
Same here.

I had it on the charger all night.. Took it off the charger and it dropped down to 92% in 15 mins without even touching it. I put it back on the charger with the phone ON until the light was green. Its been off the charger for 30 mins and I had a 5 minute phone call and its still on 100% .

Weird. Something is definitely up. I hope its a software issue(fixed with a patch) and not a hardware issue.
 
I just did a mini-recharge 1/2 hr ago. Battery is still reading 100% now after having received some emails/alerts in the interim. Plugged it in and the LED was instantly green.

So maybe you dont have to turn the phone off to get the same effect? Maybe we just need to pull off the charger and then plug the phone back in?
 
Why would gmail mail retrieval be a battery drain? There's not even an option to set up the "time between retrievals" like there is for the other accounts: facebook, twitter, etc. It's my understanding that gmail does not poll - if your gmail receives a message in the cloud, google will push it to your phone

I guess that can work too. What I'm really hoping is that the battery remembers how full it can charge to so that recharging will no longer be necessary. However, I am in no means an expert at this.
 
Thanks for the post.

I'll have to give the charging/topping off with the phone turned off a try.

I've had the same problem that my charge drops from 100% (charged over night with the phone on) to 90% in fairly quick order.
 
I think there may be a few possibilities.

1. The software in your phone that tracks how full the battery may be off and stopping before your battery is really full. This often happens if you repeatedly use it for very short intervals then put in back on the charger, or always leave it on the charger. Ofcourse you don't want to overly stress your battery by always discharging til the phone turns off, but thats something you might want to do like once a month to make sure the software can recalibrate.

2. Its very bad for a battery to be discharged too far or charged too high so as other people have said, the charger will often switch to a lower current to charge up at the end. But it should eventually get up to the maximum safe level and stop charging.

3. When your phone is idle, it is probably in some sort of power saving mode and drawing very little current. With such a light load, the load voltage will read higher. If you restart your phone, its doing lots of stuff and everything is on. Therefore it is drawing alot more current. With such a heavy load, the voltage will read lower. Maybe low enough to trigger the charger to start charging again. Then after 20min, your phone goes back to idle so the voltage goes up and it says its done charging. If this is the case, you prob dont want to do this too much and over-charge your phone.

These are all guesses, I ofcouse have no idea whats going on, but #3 sounds most likely to me.

I forgot to add that my gmail account was setup by default with the native email app also so I deleted my account from the app and just use the Gmail app now.

That would be great if thats all it takes, if not, hopefully its just a software bug and someone catches wind of it.

I like your possibilities but neither explain why I am seeing much better battery life.

#1 - That is not my pattern

#2 - Apparently the phone is wrong if it thinks 70 - 80% battery is "safe level to stop charging"

#3 - If that was the case, I would see the same battery life.
 
the problem is, some people are experiencing bad battery life with everything turned off, i get 10 hrs, and that's with GPS/WIFI/BT off, sync freq's about every hour, about 30% display brightness and mobile network off most of the time. and awake and up time's drastically different (so no stray process)

example two nights ago, charged it till it was green (about 20 minutes past green) surfed the web for less than 5 minutes checking scores before I went to bed. Turned off EVERYTHING and put in airplane mode, woke up 7 hours later and battery was at 80%....THAT'S unacceptable, and its frustrating when people just say the same trash, it's a smartphone, don't like the battery life get a BB crap, because you should be able to use your phone for 16 hours moderately (i.e. no GPS, some wifi surfing, a couple calls, a few texts, 3G on but not used, some widgets running)

PS. as a side note, i have found after a factory reset and no additional widgets, and no additional apps, I still get the same crappy 10 hours and that is with constant management of my 3G mobile network (only turning it on when I want to use it nonsense)

Good point, if you are really seeing more battery life then #3 wouldnt be it.

But #1 could be possible. I just have heard that if you have that pattern of charging, it can cause that problem. Or like with my laptop, keeping it always plugged in. But it really depends on how the software works.

I suppose in the end it doesnt matter, if it works, it works. Kinda annoying to have to keep doing that though. Kinda like filling up your car with gas with a broken safety valve.
 
I have a handheld ham radio transceiver that exhibits the same issue when charging and it is considered a firmware bug by the support community. When the LED indicates that it is full on any initial charge, you have to unplug it for a minute and then plug it back in to ensure that you're getting a complete charge.

It also has a LiPO battery, so is it really a bug or a safety net to prevent overcharging?

Doubt it. Mines been doing this every morning since I noticed it.

Just be thankful that we can exchange or upgrade our battery. Unlike some other smart phone.
