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

People should just get a spare battery charger and charg with that i got one a couple of weeks ago and my battery is much much better stays at 100 with no use for hours its great...... hope this helps.....but its nice to see people doing reserch here......
I would dred changing batteries even if it was once a week. I have a case on and it's a pain to go through all of that. It seems everyone has their own way of dealing with the poor battery life here on the incredible.

Thanks a lot. I did the bump charging technique, with the wipe battery stats in the end. How can I reset to original battery stats to avoid the bump charging? I want my phone to lie to me!!

Excellent post. Lots of information but still easy to understand. I always wondered about that initial battery drop but now I know it's nothing to worry about.

The battery stats should always be "learning," so if you just use your device normally, they will respond to that. If you want, go ahead and wipe them, but I think the effect of wiping them has been overstated. Even if you wiped them after a fresh bump charge, future standard charges still wouldn't hit the same charge state that a bump does.

Possibly the best presented thread I have read. I agree 100% with everything in post one. Confirms all of my beliefs about batteries/fixes, backed up with nice hard data.

Quality work. Appreciated.

thanks for this. really great information here that i wasn't fully aware of.

regarding chargers, i always figured usb was usb was usb considering it is a standard and all. it does seem that some chargers behave differently than others however. one wall charger i have disables my touch screen and my car charger seems to make my phone really hot. i'm guessing this has to do with different current ratings of the chargers or something. any advice with regard to this? do i only buy htc branded chargers (and when i move to another phone i have to get new stuff?). that doesn't seem right.

Pretty much, yes. Even when they claim similar ratings, different chargers put out different currents. Cheaper units will generally have lower quality control and have the potential to introduce more problems (like your experience of the touch screen becoming unresponsive).

any advice with regard to this? do i only buy htc branded chargers (and when i move to another phone i have to get new stuff?). that doesn't seem right.
I wish I had hard and fast advice, but I don't really. There's definitely a balance to be struck between the $40 brand-name chargers and the $2 generic ones. I am not well-researched enough on the subject, however, to offer a specific brand or model recommendation.

Once you find a good one though, you should be able to just stick with it; MicroUSB has become the industry standard.

The lady at the Motorola store said to me that car chargers are only for emergencies and that they dont have to be used like a wall charger. She said that she learned this at a Motorola seminar.
If you think about it, a car charger gets continous current instead of alternative current, so there must be a difference.



entirely depends on the car charger. In general no, but some are known to overcharge. This goes really for any aftermarket battery charger.

If you're charging via USB than you're safe.

I don't understand why you'd ask the question if you believe that you already had the authoritative answer.

My opinion mirrors POQbum's advice: it depends entirely on the charger.

In any regard, this is a hotly debated topic on the net. A few seconds of Googling will turn up more arguing than you could read through in a lifetime. No use in dragging that debate into this thread.

That's why wall chargers are referred to as AC Adapters.

A properly designed wall charger converts 120V* AC to 5V DC
A properly designed car charger converts 12V DC to 5V DC

No matter what, your phone shouldn't just be hooking directly into a raw power line.

Ok, so what is what you personally do? Do you often charge your phone in the car using a Motorola charger? Do you personally think it is safe and that there is no difference at all with a wall charger?
Thank you.
