battery better with PR 1.3
 

Battery definitely seems better. I did PR 1.3 OTA and have the following
- stock kernel
- at&t NYC area 2G no WIFI
- google IM always on and connected on edge
- check nokia messaging every 30 mins
- no widets other than calender desktop execution cmd

at the current time(6 hrs off charger), my battery would be at 74%, its currently at 84%

anyone notice similar improvements?

Re: battery better with PR 1.3
 

yep, definitely. atleast 2 to 3hrs more uptime. same usage than before update.

Re: battery better with PR 1.3
 

Baterry life is very very good,now

Re: battery better with PR 1.3
 

yeap, i love my battery life too, ty nokia

Re: battery better with PR 1.3
 

Do you mean this baterry life with data plan in 2G connect? :| if it is, i'll update soon :)

Re: battery better with PR 1.3
 

wohhh battery is better indeed ! Usual if i charged my phone at night.. and pulled it out the charger before i sleep.. the next morning after 8 hours it was at 75 allready.. and now ?? its STILL on the same percent !

sickk and after some webpages and messaging.. i see that the battery drains.. and if i close everything again, the percentage goes up again..

nice :D

Re: battery better with PR 1.3
 

Yeah, I noticed that too. Usually the GPS dies on me after keeping it on for 4 - 6 hours. It lasted over 6 hours on my drive to another state, on Monday.

Re: battery better with PR 1.3
 

I'd let you know if I hadn't put my phone into suspended animation with Multiboot :-/.

Re: battery better with PR 1.3
 

Saw the same yesterday night, whole night of standby and no change in battery percentage; awesome!

I am seeing better battery life on bluetooth headset connectivity as well, but need to run it for a few days.

Re: battery better with PR 1.3
 

i have also seen the same thing, battry life became better after the update

Re: battery better with PR 1.3
 

Can't say anything about battery life yet, but I think it freezes less now. (did an upgrade, not reflash)

Re: battery better with PR 1.3
 

Freeze? That's never happened to me ever. Perhaps you are running some thing from extras-devel?

Re: battery better with PR 1.3
 

I'm not so sure about battery life, as it's fine with me since PR1.2; but it seems that the memory usage is higher than before (used 20-30MB more than before)

Fyi. I use extras-devel extensively and OC'd my N900 with titan's kernel.

Re: battery better with PR 1.3
 

yes my battery also improved life now.i have one problem that is my netstory app not working on PR 1.3 any idea to solve this problem?

Re: battery better with PR 1.3
 

yeaaa, veery obvious change...... (using 2G ) and loooooooooooong lasting...

Re: battery better with PR 1.3
 

Just when I got my new phone my old phone received an important update mitigating an important issue I had with it. :rolleyes: Although a year too late I'm glad it works for you folks. I'll keep using the device over WLAN and hack more on it now. :)

Re: battery better with PR 1.3
 

Besides Battery life I cant see any other significant changes. Anybody notices any other changes?

Infact the application menu seems to have become a little laggy. I havent emmc, is it because of that?

Please let me the significant performance improvement felt by anybody

Re: battery better with PR 1.3
 

I noticed too that battery life is improved with PR1.3

Re: battery better with PR 1.3
 

This might be related to the updated PulseAudio. It's a real CPU eater, I wonder why Nokia wanted to use it with Maemo.

Re: battery better with PR 1.3
 

OK... PR 1.3 was not what we were expeting, and I didn't updated yet but, battery improviments are not a little thing... is a hard work of debugging and performance tests. Right? so, as soon as my main apps report to work on PR 1.3 I'll update. :D

Re: battery better with PR 1.3
 

is it really better or is because you have your phone clean now?

Re: battery better with PR 1.3
 

i was wondering about this as well.

the battery life certainly seems better for me with PR 1.3 (i was running virutally no daemons with my PR 1.2 setup either). however, the biggest difference seems to be in the battery remaining animation.

with PR 1.3, the battery remaining animation stays full (100%) for at least an hour after the phone is unplugged. obviously, the battery is slowly discharging, as normal, but the phone is choosing to present the information differently.

i was initially worried that the animation wasn't working at all, but it eventually started coming down. i installed battery eye to have a closer look, and the value that battery eye gives is very different from that implied by the phone's battery remaining animation.

at this exact moment, battery eye is showing 90%, which is in-line with the phone being off the charger for a few hours. however the status bar animation still shows 100% full. this disconnect appears consistent throughout the battery level range (i ran the battery down to about 20% yesterday to test it). the status bar animation is consistently 15 to 20% higher than i'd expect, given my normal battery consumption on PR 1.2 and the results from battery eye.

so... battery life seems improved, but i'm having a very hard time quantifying it.

Re: battery better with PR 1.3
 

When I had 48% with stiock kernel the battery mater read above 50%, Im running enhanced power kernel 125 600 limits, lets see what happens

Re: battery better with PR 1.3
 

the battery is better...
you guys.,.on pr1.2 my ram usage was about 150mb on start of phone...with pr1.3 its around 105mb-115mb... and 12 hours edge online on skype/fb/gtalk + mfe continuosly syncing..battery at 50%

Re: battery better with PR 1.3
 

Anecdotal for sure but I have experienced much improved battery life. I did an OTA upgrade so no change to any configuration and I have lasted a good few hours longer with usual usage. Coupled with the much better Modest experience and audio experience the N900 is finally the phone that can hold me over until the N9 next year!

Re: battery better with PR 1.3
 

One other possibility is that PR 1.3 now 'fully charges - tops up' the battery better towards the end of charging.

I had always noticed an hour after I unplug that its at 87%, now its around 95%.
But in any case it doesn't matter.. battery is increased 2-3 hours for my usage (very light, 2G, Google IM always on, no WIFI)

Re: battery better with PR 1.3
 

Yeah, me too.
I noticed my phone last a bit longer, not bad Nokia.

Re: battery better with PR 1.3
 

By "clean", do you mean "flashed"? I didn't flash. I perfomed the upgrade the way it's meant to be, OTA, so I still have all 3rd party applications, data plus whatever I had changed on my system the same way as before. Still, I see improvements in both battery life and performance.

(I notice new bugs as well. ;) ...)

Re: battery better with PR 1.3
 

Same here used OTA and the battery lasted all day
(I usually end up with a hosed battery by the end of the day)

OTA, nothing really different.:cool:

Re: battery better with PR 1.3
 

Nokia (or TI) finally fixed SmartReflex - now both /sys/power/sr_vdd1_autocomp and sr_vdd2_autocomp are available.

Good work, Nokia!

Re: battery better with PR 1.3
 

I have not so good experience, I think 3.5G drain more battery with the pr 1.3. My N900 after has 7-8 hours with about 2 hours internet surfing 3.5G and all time notify incoming email; first day after upgradeI have only 5.5 hours. I hope I'm wrong. :confused:

Re: battery better with PR 1.3
 

Kill the tracker -

tracker-processes -t

(repeat 3 times)

Re: battery better with PR 1.3
 

Yea, I did, but I have exactly the same programs as I had before upgrade.

Re: battery better with PR 1.3
 

can you elaborate on this solution as im having a similer issue , 3g is draining my battery alot faster since i flashed 1.3 thanks

Re: battery better with PR 1.3
 

I have always had sr_vdd1_autocomp set to 1, but having read that enabling sr_vdd2_autocomp is not working in previous FW I haven't enabled it. Is it possible to enable it now with PR1.3? Any known problems and benefits?

Re: battery better with PR 1.3
 

It's better than typical Nokia. The typical nokia style is to show full bars minus 1 when battery reaches 50%.

This is probably a remnant of the distant past when everyone and their dog were quantifying battery life time in terms of "wow my phone still shows full bars after 5 days!".


I've always said that the only way to quantify battery life is to run it until shutdown.

Re: battery better with PR 1.3
 

Ya battery life is so much better now. i am a satisfied n900 user.

Re: battery better with PR 1.3
 

I noticed the battery also drains faster after using 3G on PR1.3. Today, I switched on 3g to surf the internet for about 10 mins, disconnected and switched back to 2g for the rest of the day. My battery levels are considerably lower than what it should be given the same usage on PR1.2.

Re: battery better with PR 1.3
 

Both are worked in PR1.0-PR1.1. But in PR1.2 sr_vdd2_autocomp was disabled in kernel because it seemed as a source of hardware failure.

Now we can set both to 1 again and it works for me around 24h well.

BTW, from comments it looks like Nokia set sr_vdd1_autocomp by default but I am too lazy to do a reboot to check that - can you do?

I would be not surprised if power-saving discussed here can be accounted to sr_vdd1_autocomp.

Re: battery better with PR 1.3
 

@egoshin
I have edited pmconfig months before PR1.3, so I don't know if sr_vdd1_autocomp was enabled by default in PR1.3. I want to monitor behavior now with sr_vdd2_autocomp disabled, and then will toggle it on to see if it will make any difference.
