2125 - Flashing when Battery @ %50

[Guest sleewok]

I've been reading all about how if you hard reset your smartphone when the battery is not full then it will remember that state of the battery and never give you a full charge again.

I flashed my rom when the battery was at %50, and I only get about 1.5 - 2 days on my phone with normal usage. This seems to be about half of what I should be expecting. Have I messed up my battery by doing this?

I'm still within the 30 days that I received my phone. Should I return the battery and get another one?

Thanks.

that sounds like a myth i cant see how a flash update can affect your battrey the rom unstructions when flashing allways say make sure your battrey is at least 50 percent when flashing this is due to if your battrey runs out while flashing your phone could be a brick but your statment i cant see that happening m8.

At the same time, there have been many reports that hard resetting your device locks the current battery state as full. When you flash your device a hard reset takes place. It doesn't make sense to me, but that's what people have been reporting...

well to put your mind at rest i have flashed my phone many times from rom to rom and i have never had any battrey problems you have mentioned.

Its a complete myth. The charging controller in the battery decides when the battery is full not the software. The software just displays when it 'thinks' the battery is full based on voltage feedback from that same controller. This is why they used to say charge your phone for 24 hours the first time you get it. The phone says its full, but the battery is still trickle charging. These days that's not necesary either. All myths created from mixing up various instructions for different battery types, and unconfirmed roumers.

I agree it is a rumour from mixing up various instructions, And I have never hear of it with recent HTC models, but it is not a complete myth - it is a genuine problem if you flash / hard reset a motorola mpx 200 with a partially charged battery, same with the original SPV, and has been coverd many times such as:

' date='Nov 13 2005, 15:30' post='688465']The best way to increase battery life is to fully charge the battery then do a hard reset. The phone takes the current value of the battery on a hard reset as fully charged and then manages to screw up what the battery is actually capable of :)

Also Li-ion like to be topped up and a long condition charge ie over night one in a while can be benificial (just don't leave the phone plugged in to the pc with the pc switched off as the pc will drain the phone's battery)

Seriously though if you do fully discharge a Li-ion battery you will cause damage as the battery will lose capacitance, this can not be repaired in any way and the after affect will be reduced charging and usable life.

As for memory effects, L:i-ion do suffer from this but it is much less pronounced and not noticable compared to other types of batteries like Ni-mh and Ni-cd.

With the MPX200 the 'fully charged' value can be viewed / adjusted in the service mode but once the battery has reached this level the phone stops charging it giving shorted battery run time. The easiest way to overcome this with that particular handset is to always reset / flash with a fully charged battery. So not a 'complete myth'. It is also an issue with apple ipods, and again can be adjusted in their service menus, and it would not surprise me if the HTC models did also suffer from this.
