moment battery

Try using Battery Graph (Freeware) to log battery performance.

People are seeing weather apps using gps which drain battery. People are getting ride of weather channel app or changing to work with zip code rather than gps.

Charge and discharge battery fully at least 2 times before getting to worked up. Seems to take a few battery cycles to calibrate battery percentage software.

its a lithium ion battery no memory effect meaning you dont need to calibrate the battery... its already at peak performance the more you use the battery the less charge it has. Best to keep it fully charged as much as u can. Keep it on charger when at home. More you use it the more damaged the parts inside get and the ability to hold power goes down. Your best off with a second battery. This way you can maximuize the performance of both batteries and your phone.

It is not that the battery itself needs calibration, it is the phone that calibrates to the battery so this it will accurately display the battery capacity. Each battery has slightly different charge and discharge curves.

I found that when the phone reaches less than 15% it start in some kind of "battery save" mode and it takes A LOT of effort to run him down.

I was doing testing and it took me 2 hours of VERY HEAVY use (WIFI, Email, Text, Video, Browsing, Music, GPS, etc) to finally dry the entire battery

They were talking about this on another forum I'm not a member in. A battery has to be "learned"
So, when you get your phone new. And you plug it in for 20 minutes, and then take it off the charger to play with it.
Whereever the phone gets too, it thinks thats 100% for the time being. And will quickly jump to whatever the accurate reading is.

Thats why in the books, if you do read them, they say to charge the device for X hours before turning it on.
Thus starting with a full battery.
and if you want an accurate reading after that you should discharge it all the way.

its how batteries before LIon were trained hardware wise, now we have to train the software.
NIcad batteries have a "memory" of usage, so if you dont fully discharge them, they eventually stop working after a period.

i'm sure we all remember this?

Touch pro will almost immediatly go down to 90% after having it for a year.
So, dont freak out cause the battery indicatator is just reading an unlearned responce yet.

Battery indicators are NOT accurate. Ever, on any phone.
Period. =)

If your using your phone on 5% battery for 3 hours, i'm pretty sure its not at 5%.
Get my drift?


And damit, this thing needs to be here before now.
cause I dont wanna wait till friday to see if i like it or not.
Tethering is going to be a big issue for me.

ummm yeah all false... thier is no evidence EVER that suggests any of that. Lithium ion batteries have 0 memory effect. and your guage is only a n approximate on how much batter you have left. None will ever be perfect. I wish it told you an estimated how long a battery wil llast based on current use and past history but I have never seen any indicators that will do that to bad to

[petrafan007]

it has already been established at androidcentral there is a problem with the battery INDICATOR. It goes to 70% almost immediately after being taken off the charger...and 15% within a few hours and then once it hits 5%, it will stay there for a couple more hours (even w/ heavy usage) and then finally die.
