Battery Calibration Question

Hello Guys,

I am confused about this subject, I've been reading over the forums and found two deferent ways for calibration, which one should I follow?!

On this forum i found this:

Quote:

· Wipe your battery stats...
1. Allow the phone to discharge completely
2. Boot into recovery (hold Home and press On) plug the phone in if you don't have enough charge to get into recovery
3. Select Wipe > Wipe battery stats
4. Go back and Reboot
5. Leave the phone to do a complete charge (preferably over night)

And this is from another forum:

Quote:

Ensure battery is fully charged according to the OS. Switch phone off, unplug charger and plug back in. Once light is green, leave charging for another 30 minutes (light goes green at approx 95% charge).
Switch on, flash ROM. Allow first boot to complete.

Shut phone off. Disconnect charger. Remove battery. Replace battery. Place on charge, light green, leave charging another 30 minutes, yadda yadda. Switch phone on, boot immediately to recovery. Wipe battery stats.

Boot phone up. Now would be a good time to install JuicePlotter. Use as normal. Do not charge, let the battery run down completely. When the phone shuts itself off, power it back on. Repeat process until it won't switch on anymore.

Remove the battery. Put the battery back. Turn the phone on. Repeat until it won't turn on anymore.

Now charge the battery on the mains to 100% while the phone is off, keep charging for 30 minutes after light goes green. Power on. Voila, fully calibrated battery.

I've tried both procedures and found no difference between them.

I use the second method myself as it's more convenient when testing ROMs. I wipe the stats then power down and give it an overnight charge. I'll then use the handset until it's unable to power-on (as described) and then fully charge again overnight.

Slug, Thank you for your reply.

I used the first method, I will see how it goes, if it didn't work i'll try the second method.

BUT ... haha there's always "but"s

The second method says:

Switch on, flash ROM. Allow first boot to complete.

Does that mean that I have to re-flash the ROM again, or it is not necessary?!

Usually the reason people calibrate is because they are switching ROMs. You should be fine just wiping the battery stats if you're not switching ROMs.
