Battery Issues don't seem to exist on Developer Gift Model

[Daegalus]

I was able to get a Nokia Lumia 800 as a developer gift from Nokia. and it seems that it doesn't have the common battery issues that people have.

At first it did, would shut off at 20%. Messed around with just connecting and getting data using DPM and Nokia Care Suite after updating it to Mango 8107 and it started working just fine.

I am on the 11451 firmware and my Diagnostic app steadily always shows 1516-1520mAh for full charge. Only thing weird, it says "Charged 65535%" for the battery percentage. I have checked it daily for the last week, no change to the full charge capacity.

Here are my specs to help, and a shot of my phone's diagnostic screen.

Carrier: AT&T USA
Firmware: 1600.2479.7740.11451
Hardware Revision: 112.1402.2.3
OS: 7.10.8107.79

Nokia Care Suite Info
Product Code: 059J3G0

At some point I was able to pull the Variant and it was something like "RM-801 EURO MATT BLACK" or something, I can't find it atm. I think it was in DPM, but I updated my DPM and it won't launch now.

Also, there isn't an 11500/11501 release on DPM for this model, or on Zune.

I thought this could be useful for those trying to figure stuff out.

Images of my Diagnostic app:

Well, there are (were) 2 problemes.

- First, some people had less than 1000 mAh for Full Charge Capacity, when the battery capacity is 1450..

- Second, people have around 1500mAh like you, but, "Remaining Charge Capacity" stuck at about 1300 when the phone is FULLY charged.
THere is a difference of 200 mAh.

I bet you are in the second group.

The update fixe both problems, and the new Diag app show correct percentage of charge.

 

[Daegalus]

Ok, I will look into it. I just thought I could provide some info that might help somehow.

I will full charge it and check.

But the second issue, is there isn't a 11500 update for my product code on the servers.

Does anyone know which one would be safe to flash onto my phone if I wanted to do an upgrade? The closes I think was I got UK Variant MATT Black, that didn't have any carrier specifics on it. I didn't flash it, I just have it downloaded, and changed the Product Code on the filename so it matches mine.

Just wanted to make sure that I can flash safely one of these other versions so I don't screw up my unlocked phone or make it default to some settings that don't fit for the US market.

For 11501, I used Navifirm Plus to flash "Country variant United Kingdom GB v3 Black (059L7C2)" without any ill effects. As you mentioned, I changed product code on this firmware to match my phone before flashing. I have a debranded Tmobile Germany phone.

Note that 11501 includes the Network Setup app. It won't hurt to add your carrier's APN settings using this app -- here is AT&T's apn:

Before I do the upgrade, is there a way to do it without wiping my phone? If not, I have looked through the various backup tools in the other WP7 dev forum, but does anyone know which one, if possible, can backup and restore everything. Apps, settings, etc. to the way it was before the wipe?

Also thats funny, since thats the exact version I downloaded, thinking it would be the least likely one to screw anything up since it seems more universal then the carrier specific ones.

[Edit] Oh and forgot to provide an update. I did a full charge, and it stopped at 1380ish or something. I forgot to check this morning after a full wall charge, but 1380 is what I got from charging it from my laptop. So I guess I may be in the same boat. At least it doesn't shut off at 20% like it did when I first got it.

 

[geekaren]

Nope, sorry. Doing the firmware flash will wipe your phone.

The update fixe both problems, and the new Diag app show correct percentage of charge.

The update may or may not fix both problems. Some people are reporting better battery life, some people are reporting worse. Also, the incorrect percentage (65535%) isn't a problem with the Diagnostics app - it is a firmware issue with 11451. I know this as I kept the old version of the Diag app on my Lumia after updating to 11500 and the correct percentage was shown.

I am on the 11451 firmware and my Diagnostic app steadily always shows 1516-1520mAh for full charge.

The full charge capacity and remaining charge are different. Everyone I know who has a Lumia can not charge up to the full rated capacity of 1450mAh. Most people reach around 1280mAh and it stops charging.

After the 11500/11051 update, you will see it will charge up to ~1470mAh for a day or two. And then the available capacity will start to drop off and stop around 1280 - 1320mAh. No one knows why this happens as of yet.

You can flash any version on the Lumia firmwares to a Lumia - they should all work. Just some of them have different pre-installed apps and different default language settings, etc...

I got a pre-release model of the Lumia 800

The battery problems were present all the time, untill I did the last update
Now my full charge is allways 1350 mAh
And my battery lasts about 2 days.

I replaced my firmware on my developer gift phone with the new firmware and lost all my debugging tools

Any chance you have the dev firmware or the KITL/QC BSP xaps?

At some point I was able to pull the Variant and it was something like "RM-801 EURO MATT BLACK" or something, I can't find it atm. I think it was in DPM, but I updated my DPM and it won't launch now.

I Have the exact same situation now coming from 11501, with very poor batterylife, I also flashed the MATH BLACK variety which was indeed on DPM. After that I received a Zune update to the latest OS but the firmware is exactly like yours and also the diagnostic tools says "Charged 65535%" all the time.

However, my batterylife is great and I have not experienced any bugs yet, alltought the touchfunctionality seems to freeze every once in a whilw e when incall. I sometimes have a problem ending a call.

I can live with this, this is the batterylife I need, a full day with sub heavy usage. 15 calls, some long, two exchange acounts, a pop acount and wifi on all day. also browsing every day and twitter and facebook automaticaly update.

Hi.
I've same version with similar problem. i thinks diagnostic display 1500 mah but it's a fake display. One time i've see the true (i think) value : 908 :/
Often, near 40-30% of batterie my lumia shutdown. In reality, battery was empty ...


I've flash with the last firmware yesterday and all work well and battery level too!!

Can you tell me the product code of your dev model?? It will say on the underside of the SIM tray...

Thanks

My dev model is RM-801. Got the 8107 OS update, but no firmware update is available to me so still on 11451 there. No clue if I have the battery problems or not. I don't really want to know.

Which debugging tools

I've flash with last firmware, unlock with windows phone tools and i can re-develop and debug.
(i've use this tuto to install last firmware http://www.monwindowsphone.com/tutorial-comment-debrander-son-nokia-lumia-t9709-10.html)

RM-801 is a generic code for all Lumia 800's in Europe, Asia, and Africa. What I want to know is the specific product code related to the developer model. It is a 7-character string, eg: 059N2C3

You can find your product code on the under-side of the SIM tray...

A bit lazy to take the SIM tray out, but on the box is written 002X5P9. Probably the code you're looking for.

 

[CervezaPorFavor]

My developer set product code is 059J3G0, which is the same as yours.

Nah, that's not it. Don't worry about it though...

Awesome, thank you! Can you tell me what developer tools come preinstalled with the phone??

Cheers

There are no developer tools as far as I know. It's just a vanilla Lumia 800 phone.
