Battery draining and resetting at 36%

[Guest Markda2000]

My Mda Pro has for the last couple of weeks decided to resest at 36% charge and then will die altogether.

My use of the device is the same as it always has been and is where I would expect 36% charge to be.

ie I don't think the battery meter is inaccurate.

Anyone else got this problem? and do you think Tmobile would send out a replacement bettery.

36%? Mine was 41% yesterday - and only in the past couple of weeks. Ussually fine until I receive a text or send an email then it resets and wont reboot until plugged in.

Thought it might b because I was out of memeory but have replaced the ROM and wiped the machine and it's still doing it - VERY frustrating.

How old is this and how heavy it was used?

It certainly feels like deteriorated battery.

[Guest Confucious]

Mine's just under a year old and quite heavily used :rolleyes: Look's like I need a new battery but less than a year isn't good.

[Guest Ingvarr]

Another possibility is a faulty or badly designed battery calibration software.

Looks like battery capacity is reduced (and it should, after that time), but PDA doesn't "learn" about it, it still thinks battery is like brand new and so it overestimates the runtime. Hard reset, removal/wait/reinserting of the battery, and making the full discharge cycle may help.

Though when battery is very deteriorated (near-discharge voltage is still nominal, but battery can't provide the needed wattage anymore), its often the same sympthoms (early shutoff), so its hard to tell.

Hi,

Over at XDA Developers forum - there have been hundreds of posts about this issue (About 4 threads)

The net result is that you need a new battery! Thats all thats wrong - the ROM is fine, the unit itself is fine - its just the battery is not providing enough power to the unit so it resets!!

Well cant be 100% sure but thats the consensus of opinion.

I rang Tmobile regarding mine, and they checked the warranty (2years they stated) and sent a battery out in the post, with out any debate.

Great service Tmobile, Like to see that from Orange.

Mine's an O2 Exec but I bought it off eBay so don't have a warranty - looks like it'e eBay again for a battery.

[Guest lowbug]

I had the same as well rang orange and it turned up the next day :)

[Guest MECX]

Vodafone made me send the whole unit back even tho I told them it was the battery at fault :-S

Should be getting a new one tomorrow tho :-)

[Guest MECX]

lol Vodafone sent me a brand new Universal but sent the same battery back, i did tell them lots that it was the battery not the phone.

Oh well my old one had a dent in the top and the screen was rather wobbley, think Im just going to plump for a new battery from ebay, can get them for about £5 ish.

[Guest Jasonkruys]

There has been varied success with batteries from ebay. I have had a couple that werent much better. In the end I plumped for a genuine original one from expansys. More expensive at about 40 quid, but no problems since..

[Guest Wildfire]

I have had this issue for sometime now, mine is out of warranty.

Spent £15 on a new battery and the issues went away, it would seem that betteries for the universal is not that long lasting.
