[Q] [ME70C] use without battery - MeMO Pad 7 Q&A, Help & Troubleshooting

Do you know if it is possible to power on the tablet after removing the internal battery?
(i'm not asking if it is possible to use it while the battery is charging)
I know some mobile phones have some sort of "protection" and do not turn on if the internal battery is missing or defective.

I have problem with backup battery

I have O2 XdaII i Back up Battery 100% on screen but i remove main battery then i insert main battery into the phone it run customizing.
Someone know help me!!
I have same problem my friend
I have the same issue. I called O2 support and they told me that i need to change the backup battery. It must be the hardest battery to find and once you do find it you have to hope that that is the issue and not something else. Here is the only link it the 'world' i was able to find and I believe this is the battery we're after (copy the whole link in the IE or it will not work):
http://www.services.foxconn.com/store/Product.asp?Category.Id={015B5282-CC34-4E0D-BD91-D97EB366CA9A}&Product.Id={9372B82C-A96C-494D-8F9E-BFFD3EF70E2B}
Let me know how you went with this.
It looks like a button cell / hearing aid battery...
Not sure, if shown battery will fit. I didn't dig Alpine, but Himalaya has Maxell CR2016 rechargeable lithium battery.
XDA IIi backup battery
As far as I know there is no separate 'hearing aid' type back up battery for the XDA IIi - it uses persistant something or other - i.e. it draws power from hte main battery and uses Flash Ram. I have a regular problem reporting backup battery low if I have charged the battery separately from the XDA on the cradle and then inserted it - It seems that the back up only charges when the XDA itself is put on the cradle

Hot-swapping batteries?

Hi,
While I'm waiting for my spare battery to arrive, I thought I'd check and see how useful it's going to be...
Is it possible to swap batteries without having the device 'hard reset', or can I quickly swap when I need to without having to reinstall and setup all my stuff?
Thanks.
Swapping the battery is like soft resetting.
Power off - power on
I don't think anything is lost. You just reboot the phone.
This will never be possible. You have to keep up your power supply during the battery swap. This is only possible with a large capacitor. And only for this use you will never see this built in a mobile handset due to the extra cost, weight and needed space.
While taking out the battery the device will only power off. After replacing the battery you can normally switch on your device, this is like a soft reset! Don´t worry about lost programs and so on.
That's what I wanted to hear - I don't mind a quick power-down to swap, I just didn't want to then have to re-sync with the computer to get all the settings back.
I suspected the \internal storage was flash-based so would survive a battery swap, I just wasn't sure about the main memory - my old XDA would lose everything when the battery was low.
Thanks all!
I don`t know what happens if you swap the batteries when the device is on external power - maybe that works.

Windows Mobile does not lose the data on power-loss since version 5. Devices up to WM2003SE held data in Ram and lost all settings and data when the battery was empty.
Some devices had a small auxilliary battery which held the data when the battery was empty.
Have fun!

Battery drain when rebooting phone

I have 2 batteries and one broken phone, I use the broken phone to charge the extra battery. If I reboot my phone with a battery with a perfectly good charge when it reboots it shows the battery is dying? If I put the battery in the other phone and charge the status says the battery has a charge, not sure what is wrong?

My guess: Your broken phone doesn't actually charge your battery or at least, not fully. It might think it's fully charged at a very low %.
It could also just be the os not reading the charge correctly. I've had it happen on numerous occasions where I'll reboot my phone and the charge drops by 20-30% after reboot. But if I continue to use it without charging or rebooting the percentage will eventually increase or at the very least stay at one level for an extended time.

Well when I take it out of the broken phone and put it in the good one, the good one says its fully charged too. The only reason the charging phone is broken is cause the IMEI is toast.

It doesnt increase, just dies......... tried charging the battery to 100% turned off then ran battery optimization app, used the phone for a while and rebooted it at about 60% and after the phone rebooted it said the battery was at 2%

You should probably stop rebooting, let it die and fully charge it. Might need to recalibrate your battery stats too.
As for your IMEI being toast, you can flash stock KK4 to fix it.

Thats what I did was let it die and fully charge and used the battery recalibration app to change the stats. then rebooted later and lost all my battery?
Have tried flashing stock KK4 with no luck on it, now its just an expensive charger

Ok.. maybe we've been missled this entire time. What's the highest battery consumption in settings->battery?
Also, you could get betterbatterystats app to help trigger what's draining your battery.

Well what I'm starting to think is that the way you charge your battery has nothing to do with it. The OP missled me to think that it was coming from your broken phone. It might come from your phone (or app/setting on your phone).
Imo, backup your apps and such (after finding out what's draining your battery), flash back to stock and start from there to get back to your ROM.
How old are the batteries?
Do they both report the same percentage immediately after boot and after comparable use for a similar amount of time?
They are only good for 500 to 1000 cycles. A dying battery will appear fully charged when on the charger but quickly drop to a lower voltage when used.

Looks like the major drain on my battery is MediaScannerService and AudioOut_2?

Eh yeah, I would highly suggest backing up, going back to stock and reflashing your way up.
MediaScannerService is probably cause your SD card is a mess, a factory reset usually helps for that. AudioOut_2 is weird though, do you have clicks sounds on?

Run a full battery cycle without it on. I'm pretty sure I saw this issue before.
For the media, it can be a few things but cleaning your SD card can help a lot.

What's the error? You external might've been the problem all along. I would suggest to copy the files that are on it to your pc and format it, see if it works.
Wipe battery stats in clockwork mod recovery and check. I hope your issue might resolve by wiping battery stats..

Connect it directly to your pc (not through the phone) and see if that works. I'm pretty sure your external needs reformat.

[Q] Battery issue on new phone

Hi, I just purchased a razr i and I am not sure if there's a problem with the battery or if what I am seeing is usual.
I charged the battery fully when I opened it, it then discharged fully within about 8 hours. I fully recharged it, and agaiin it fully discharged in about 10 hours. It is not connected to anything (I don't even have my sim card in it yet), so cannot understand why it is discharging so quickly , especially as it is not doing anything!
As I haven't put my sim in yet (I need to get a new smaller sim card to fit it), could this be causing an issue ? I don't know if maybe its constantly trying to find a network and this is causing the drain problem.
If anyone can shed any light on what's happening here it will be appreciated. I don't want to get a new sim card CID I still get this issue and the have to change back again, and I expected the battery to last a long time based on what I have read elsewhere.
Many thanks
I had the same problem on mine. Check your battery readings, I think cell standby eats up a lot of battery when you don't have a sim on it

Try it in Flight mode for comparison.
Thanks, I'll give that a try and see what happens
There doesn’t seem to be an awful lot out there regarding having no SIM card inserted and rapid battery drain so I think it’s worth a shot.
I think it would also be worthwhile to download BetterBatteryStats to find out exactly where and what is draining your battery, and also to turn off Google Now (with or without a SIM).

Yes, phone manufacturers say this, that your phone will constantly look for a network if one is missing, it does drain the battery significantly. So maybe try it in aeroplane mode and see how the battery goes. Also consider how many hours the screen is on. The screen is typically the biggest battery drain.

It is just time to solve my phones problems.

Twin processor and twin batteries. The twin procs shows the time, but the accu does not. I want to toy little bit of this.
Twin proc power.
It just need an little bit peekin after fusions famous rom. Liittle bit peeking
It is pretty bricked. but things goes right!! I like this trin proc handheld

for example. just keeping it standby. it is like full charged after few days. full charged indicates this.
Ok. Take one call or do anything with it. the battery charge goes logaritmically to zero.
What you think?

The battery shouldn't drain that quickly, something else is wrong; the battery might have dimineshed capacity to hold a charge, or you're experincing the 1 GHz bug (reboot with wifi off).

If you mean that cpus run at 1Ghz continuous these runs 200Mhz both I ssh logged to the fone. I think it is battery problem. I have two of this kinda of these: EB-FM7FLU . 1500mAh (hah!) Might be original. both batteries.
I use in several apps these batts, so I think how Li-Ion(Lions) work. Battery drains of course, but never just like this:
Full charge - do something - logarithmic drain to zero.
I need to call to the Samsung service (with my phone:d) and purchase !Li-Ion! accu for this
Said wrong an previos, never serial, but parallel. Serial switch kills the phone parallel does'nt sorry bad english
I try to flash Omni rom later some day.
Remove charger - go - answer a call. - battery dropdown.
Someone testet direct cable from transformers's secontary to handhelds pinouts?
