i dont think that the backup battery on your phone can be used litterally for as backup when your battery is drained out, i think the only purpose of this battery is for the saved settings on your phone, so that when you take out your battery, your saved settings wont be erased. i'm not quite your if i'm right with this. moderators / mpx200 experts pls. confirm.

There is no backup battery. That indicator is just an oversight from the PocketPC OS, upon which the Smartphone OS (Windows CE) is built. User settings etc in Smartphones are held in non volatile RAM.
If you notice, the indicator never changes from 90% -------------------- It is by caffeine alone I set my mind in motion.

There is a backup battery and it is located at the main circuit board of the phone.
It is shown in this picture I took here.

Interesting... so this backup battery just saves the critical info when the main battery is fully drained right?

Hmm... Seems I was wrong then.. How embarrassing!! :oops: :oops:
Still, I'm sure I'd read somewhere that there was no battery and that Moto just didn't have time to remove it from the OS... It does begger one question though... How come it's reported life never changes from 90%? I'd guess the battery there is not actually the same battery as the one being reported in the OS, which would make sense as the OS was originally designed for PocketPC's which DO have a proper backup battery... Plus that battery looks awfully small.. I suspect it's just for the clock and other critical data really is held in flash RAM...

The battery shown in that picture is not the "backup battery." That battery is only to keep the phone's time, just like there's a battery on the motherboard of your computer to keep the time. The flash memory on the phone does not need a power source to retain it's information. The "Backup Battery: High(90%)" is not referring to that battery, nor does its power measurement match that battery.

It is still classed as a backup battery though.

yeah I would consider that a backup battery too. I mean thats what it does, backs up the time and simple info like that. Same as with many other products like my calculator, the backup batter is there to help retain info int he calc. Once i let my calculator sit for a few years without giving it a new battery and sure enough the memory that i put into the calculator was erased. I'm pretty sure the same goes for these phones, and as far as the 90% indicator, could be possible that the battery doesnt drain too quickly as with all those "watch type" batteries, and the backup battery is only going ot take action once the main battery is completely drained and even if your phone doesnt turn on because the battery is drained doesnt mean every bit of the battery is drained theres always some juice left in there. it just doesnt have enough power to turn on but it will have enough power to keep everything "alive". because when i mean completely drained i mean COMPLETELY drained which is very very very rare.
another possibility could be that the backup recovers once the main battery is back in or once you charge your phone. and maybe thats why it shows 90% because i have read somewhere that when you recharge a battery thats not a rechargeable, you cannot recharge it 100% or else itll start to leak if it goes anymore, you can however charge it less then 100%. once your phone is drained your not able to see if your phone is using the backup so we actually never know if that 90% drops oh boy... another long post by me... sorry... lol, guess I wrote another book, I'll publish this one in paperback. -------------------- See what you believe, don't believe what you see

To add to that, a Pocket PC has exactly the same type of backup battery.
The only difference is the design due to size. -------------------- Smartphone and PocketPC History

Hi Guys,
My 200 was loosing date and time when the main battery was pulled, and I've moved on to a V3x for about 6 months, however my wife needs an upgrade, so out with the 200 for her, it's dead, main battery has 3.8 volts, that should be ok, so I've followed the guide and got to the backup battery, it's a SANYO ML614, went to several watch/jewellers, the've never heard of it. It's not surprising, it's a lithium MANGANESE dioxide re-chargeable 3V, NOT a button cell, all the jewellers said bring the battery in and we can supply an equivalent, I don't recommend putting a non-rechargeable battery in a charging slot. Sanyo has supplied a phone No for a UK distributor, will try this AM and let you know. Max. Nope, no good, unless I want 500 of them, does anyone know a retail outlet in the UK for them, I've seen one in the States but they don't ship abroad, I've also googled around without success.
