Beautiful (battery killer?) Widgets

I had the beautiful smaller home widget running and have applied the UV kernel on my cyanogen rooted N1 but my battery life wasn't that great. I would get about 24 hours before a charge but without using the phone very much. I uninstalled Beautiful home and now my battery life is brilliant. I charged before going to bed, it was at 90% when disconnected. I left it all night - screen off, display dimmed all the way and it only dropped 5% in the 9 hours it wasn't doing anything. It has been on and off all day today with once 2 minute call, a couple of texts and 10 minutes surfing, wifi and 3G. It's dropped a further 9% so far. That's from 7am till now, 1637HRS. I have setcpu running and process manager set to kill running apps every 5 minutes. Set cpu only has the charging and sleep/standby profiles set. 652 max for charging, 576 max for sleep/standby. Power manager is installed but I removed all the profiles from that. Oh and my screen has been at mid brightness since 7am this morning too.

I did read that some widgets and such like apps/themes are not very kind on the cpu and battery fronts. Is there an app that will show how much each widget is consuming and what amount of cpu it's taking too - as well as network activity? I think process manager may do that but the UI isn't great in that section of the app.

battery left shows the shake them all live wallpaper that i was using that obliterates the battery, im pretty sure it calls the default android battery use page that summarizes the usage.
[Nexus One General] Highland3r:
36+hrs with standard usage (email/txt/few calls).

Good 3G signal when away from home, otherwise wifi.

Screen on lowest brightness indoors otherwise med/high outside in sunlight.

Don't have a load of widgets running, news and weather refresh hourly and not using live wallpaper.

Running stock N1 on O2 UK.

Wondering if the battery life difference depends more on how the phones are charged rather than the model number?

Do people with better battery life charge via USB (or another lower output method)?

Found the best life was with a low output charger rather than using a 1A standard Plug -> USB adapter jobby. *shrug*
[Nexus One General] DarkDvr:
2 questions..

1. how much do you use it throughout the day?

2. how long how you had the N1 for? Did the battery life improve?
[Nexus One General] mathieu92:
Got the F serial too, from the first day. Actually using stock (no Oc or Uv kernels) CM 5.0.5.3 + NexTheme.

I use the phone moderately. ie couple phone calls (15 mins/day), couple of texts (10/20 a day), email, gchat, rss reading (30/45 min a day), games (20 min). Also random use of Pandora, video podcast and such (not on a daily basis)

GPS off (only on when needed...).

I was getting around 10/12h before battery fully died, during work days. I have a really weak signal out there at work (T-mobile) and the phone is constantly switching back and forth between 3G and Edge.

Since I have installed Locale, and set it up to use Wifi, when at work and at home, it is way better. ie, I still have 60ish% after the same 10/12h. I dont mean Locale was the trick, but that Wifi use instead of 3G/Edge saves a lot of power, especially in weak signal zones.

I dont try that often (usually plug the phone in every night), but I have managed this week end (forgot to plug in) to get something in the 24/26h range, with more phone calls and less use of the screen than during the work week.

Looking forward to 5.0.6 as people are reporting nice battery improvement on test1 version.
[Nexus One General] Russ T. Nail:
battery seems to be getting worse by the day and i'm very aware of what i'm doing with it. I've been thinking about getting the 3400 battery because of how annoying it is to constantly have it plugged in.

Ends in F. If that's the problem I hope they get some kind of recall on this.
[Nexus One General] hah2110:
Those of you that are saying F with great battery life... when did you get the phone?
[Nexus One General] mindfrost82:
My P/N ends with a B. I vote for mediocre battery life because I can probably get 24+ hours out of my battery with light-medium usage but exchange push email on as well as weather and facebook updates.

If I have the phone on a lot, then my battery life starts to go down, so I would say if I did heavy usage, then I would probably get <12-15 hours out of it.
[Nexus One General] disgustip8ted:
i just wanted to toss this out and reiterate it, i have used both an F and a B handheld.... they both had decent ~10 hour battery life with moderate usage if i wasnt doing stupid stuff like streaming music all day

should have an option in the poll that you have used both and didnt notice a difference lol
[Nexus One General] ram130:
I HATE MY BATTERY LIFE...its now 11hours since I took it off the charger at 5am. It was on 2G only, everything else off when I was at home. Lost 5% in 15mins!!. Then my day started at 11am with 3G enabled and so far only made like 30min worth of calls. Light reading on the train in airplane mode for about 20mins, played some music for 5min and check my bank accounts for 3mins. Come on now its 4pm with 35% left!!! YOU GONNA TELL ME THIS BATTERY IS NORMAL..its bloody G1 battery type life we getting...
[Nexus One General] DarkDvr:
I'd like to mention that there are 3 more pieces of information that could help us determine what's going on here.

Guys, please install a free widget called "Battery Left". it estimates your battery life upon monitoring your battery use over several days.. but the reason we need it is this:

It has a Battery Voltage, Battery health and Battery temperature.

My battery life is ain't great, first 50% are burned within 2 hours. Last 50% take about 4-5 hours. I have:

PN ends in "B" (bought the phone a week ago)

Voltage: 3708-3781 mV

Health: Good

Temp: 31.5 C
[Nexus One General] vegetaleb:
I wonder if Task Manager eats battery too knowing it's always ON and tracking any OS or apps activity...:confused:
[Nexus One General] hah2110:
If this was true... why would it not register in the "battery use" section of the phone? Doesn't make sense. All of these claims of "rogue" apps but they never register in "battery use"?
[Nexus One General] ussuss:
Hi,

I just installed Battery life by James N from the market.

After unplugged the phone 4 h ago, short browsing on market and checking mail and 1 h of music play I'm a 85%. I normaly get about 10 h with normal to high use but i have only a week with the phone so i don't know if it's normal.

Battery Life:

Health: Goog

V: 4011mV

Temp: 26 C

Running stock rom, Wifi on, display on low.

I don't know if this is a normal traning rate for the battery/phone, have anyone else have better or worse experience on the training rate?

I will report back tonight with todays battery drain.

/Linus

Rogue apps are different from rogue services
[Nexus One General] Rusty!:
1. On one of the impressive times, it'll be during the week when I'm at work. Lot of it sleeping on the desk with a few calls and texts, GoogleMail push, one IMAP account polling every 15 mins, finishing up with a couple of hours wifi in the evening. Very comparable to it's predecessor, a Nokia N95.

2. Ordered on 20th Jan, don't think it's changed much since then.
[Nexus One General] disgustip8ted:
is that your mV at a full charge?

this is what i suggested a few pages ago, battery left is a great widget, when i undock in the morning ive got 4177mV or 4181mV at a full charge. on the 1x1 widget i have system battery % as the main text, voltage as the secondary text, time dead as bottom text. gives me a very good idea if I should have the device plugged in based on what i am doing at the time.

its a phone, not a nuclear power plant, if you've got a lot of stuff going on and running its going to drain the battery, otherwise get that sedio 3200mHh battery and deal with the 6mm depth increase.
[Nexus One General] Raymond77:
The battery life is toilet on this thing, and is ultimately what is swaying me towards putting it up on Ebay.

I need a phone that'll go longer than a day, and this just doesn't - unless I don't use it at all AND it's not moved from location to location (on the move it just can't hold onto a 3g or HSPA signal, and the battery drains much, much faster).

I've not had a battery this bad since my last HTC phone...:mad:
[Nexus One General] Rusty!:
Nothing at all after a huge gap:

like so?
[Nexus One General] hah2110:
There is an F at the end... Lol... You have the F.

Just got my replacement. Product # is 002-01 with NO letter. I'm going to let the battery go for a little and see how it does.
[Nexus One General] disgustip8ted:
I dont think its that bad persoanlly, I've had a couple different phones and all had to charge about once a day with what i was using them for, maps, email, music. To each his own I guess, too much power within the phone to handle.

Out of curiosity, what other phones are you comparing the battery usage to and what was the mAh the battery for that phone was rated at?
[Nexus One General] Rusty!:
I know that one's an F (not mine for the record, however as stated, my one is also an F) but it was just to make sure no-one is discounting that letter due to the large gap between the P/N and the letter.
[Nexus One General] hah2110:
Gotcha... Mine has NADA after it! Battery actually seems a little bit better. I've dropped 3% in about 1.5 hours. That isn't bad by what I used to get. More to come.
[Nexus One General] Lancealot:
Create a standardized test. Say charge your device then leave it in recovery for an hour and reboot to get battery percentage.

.02

Cheers
[Nexus One General] hah2110:
I happen to like this idea... Anyone in for it?
[Nexus One General] Lancealot:
I was in recovery for an hour and my battery went down to 92%. Amon_RA 1.7.0. Battery is a two week old OEM that rarely has partial charges.

How's everyone else looking?
[Nexus One General] DarkDvr:
I stand corrected, I got a B.

I measured my time overnight today without touching the phone:

BT, GPS :: OFF

WiFi :: ON (but should be auto-disabled while on standby)

3G all the time

100% sleep

and I lost 20% for 5 hours. So that's a 25-hour battery life in stand-by.

Well, I thought about it a lil' today.. So the TouchPro2 that I had before this would last about 1.5-2 days with easy-to-moderate usage.

Thinking that N1 has a bit bigger screen, twice the processor speed (and I'm gonna wildly say twice the power consumption).. Plus, I use the phone more since it's a new and awesome toy..

And I guess there you go - 10-12 hours of battery life. Although that does seem kinda normal to me from my own PDA experience, that's exactly 10 times LESS than what Google claims:
[Nexus One General] gizmo2431:
great thread, hopefully we find out some good answers. they warrantied your phone off of poor battery life?
[Nexus One General] DarkDvr:
I'll assume you're asking me..

Since I bought it 2 weeks ago, I think I'll just get the same phone if I exchange right now.

I wanna wait for 2-4 weeks before I change it so the, hopefully, they'll have enough time to find/fix the problem... maybe even deploy/ship with FroYo.
[Nexus One General] ram130:
Well I decided to limit my usage just light things today like texting for a total of 45min and 37min worth of calls so far today. Browse for like 10min. I unplugged it at around 11pm last night and so far its now 6pm.

In other words, its been over 19 hours now and I have 8% left.:eek:

Battery stats:

Good health

33.2 C

3.654V (was at 4100V when it was at 100%)

Had the phone since FEB 25.

Now if only I can get this type of battery life with moderate usage..:rolleyes:

WHO DO YOU GUYS THINK??

Good idea..when I reach home..
[Nexus One General] DMaverick50:
Wow ship a nexus one with froyo? Don't g1's still ship with 1.5 or older? Well I guess since its straight from Google its not impossible. anyway what's the eta on froyo? Don't we usually start hearing actual features a good while before the ota? I fear we are still looking at months yet?
[Nexus One General] brosen:
That means you are loosing around 4% every hour, I am doing the exact same test, only Wireless and 3G on, with the phone is in standby mode (screen off). In three hours I will let you know if my battery capacity went down 12% to 88%, I just removed the phone from the docking station at full charge 100%. Well I just found out the phone is receiving some emails, but that shouldn't be a big deal, I will not turn the phone on.
[Nexus One General] ram130:
Then again in recovery, the brightness is FULL.

I am on stock, so how will this test work for me? :confused:
[Nexus One General] hah2110:
Are any of you guys that have extraordinary battery life willing to send someone a nandroid backup to put on their phone to see if it is something software related? On a side note - can you move a nandroid backup from one phone to another? Otherwise, my idea is moot.
[Nexus One General] DarkDvr:
I don't have G1, I have Nexus One. It shipped with 2.1 update 1. I'm pretty sure when FroYo comes out, new N1s will ship with FroYo installed.
[Nexus One General] DarkDvr:
Ok well, as Lancealot suggested here, we need a standardized test. Problem is, many phones aren't rooted (like mine), so recovery mode is not available/too scary =)

So, here it is (takes 10 minutes):

Set screen brightness on FULL.

Set phone in 3G mode

In wireless manager widget, turn ON everything (WiFi, BT, GPS)

Turn OFF sync (in wireless manager widget or in settings). So that no emails sync. Too many variables there.

Launch Map, Browser, then go back to screen. Do NOT kill apps with any app. Let them run in background.

Write down your current battery level.

Launch Camera app. Put the phone on the table, so that it's pretty dark in the camera view.

Periodically tap on the screen, it dims about every 5 minutes, so it won't be too much trouble.

Wait 10 minutes, don't let it dim.

After 10 minutes, fill out answers below:

Started 7:56am EST with 80% battery life. At 8:06am EST, I was at 77%; although, it dropped to 76% within a minute. This is terrible. 4% in ten minutes? It shouldn't happen.
[Nexus One General] disgustip8ted:
depending on the live wallpaper, yes, it can demolish your battery

for instance, the live wallpaper "shake them all", while the wallpaper is super cute and ultra happy fun time, its just too much of a battery drain to have on all the time. it is more of a novelty.

BTW, this is pretty standard battery drain in my experience - I usually use about 10% web surfing for 25mins on the way to work, for example.

That said, my phone easily lasts 3 days in standby (2G) if I don't use it much, which is totally fine (good in fact) in my opinion.
[Nexus One General] MaxiJavi:
Can say I even had bad battery life, but ...

I conditioned the battery based on instructions found on this forum.

Then I would get a good 35+ hours on moderate usage (3g, some video every morning on the train, browsing, MP3, etc).

However, I flashed the AVS kernel a couple of days ago, and I am at 64% after just over 24 hours of fairly heavy usage ...

Which is is absolutely awesome :-)

I am running baked goods 1.1 and intersectRaven's AVS kernel.

No live wallpaper, but juice plotter, fring and a couple of other background tasks.

Screen at 60%

I'll try and do the test and get the serial when I get home, I bought my phone in March.

[Nexus One General] DarkDvr:
Well, I did a long-term testing (overnight) and my drain is 20% per 5 hours in full standby.

it should be 20% per 50 (fifty) hours per the specs.

Called HTC support (real nice support by the way), they immediatly agreed that this is a faulty battery and they will send me a new one immediately. I don't have to send my battery back to them (wink, wink).

I'll get it in 3-5 days, charge it per instructions (12+ hours on AC, with phone off).. will report if there's any merit to this exchange.

wifi

Hi guys i think that the problem stays with the wifi.

Im still doing tests, but the facts are.

Yesterday i unpluged the phone from the cord at 7am and at 3 pm the battery was at 8%

Today i unpluged the phone at 7am and at 00pm im still having 19% of battery.

-P/N - F

-Rooted

-Using last CM

-I'm handeling several calls

-push mail for exchange allways on (30 notifications per day)

-push mail for gmail (10 motifications)

-gtalk allways on (some casual chat - 5 times)

-some browsing 5 minutes

-some google maps 2 minutes

-3G allways on

What changed??? I turned off the WIFI. I'm only using wifi at home, all the day i was using the wifi on but it was not connected. it seems that the wifi solved my problem.

Tomorow i will try again with wifi on, just to be sure.
[Nexus One General] Cynicism123:
My P/N ends with an F, sadly. My battery usage is terrible.
[Nexus One General] DarkDvr:
Nah. They'd lie about 10-20%, but they won't release a device that lasts 25 hours on standby.

The dude in support told me that they had quite a few calls and he says replacing battery seems to fix it for people. He said that they never had a case where it was the phone that was at fault, always the battery.

I know, I know, support doesnt know much and all that.. but there it is.

We'll see how the new battery operates.. with proper first-time charge..

By the way, he said that he's pretty sure that letter has nothing to do with battery drain, but they do have problems with batteries being defective.
[Nexus One General] DMaverick50:
Are you sure there's a "proper" way to charge the first time? I posted a thread about my poor battery life and the consensus was that with these types of batteries the first charge is not significant and subsequent charges don't have to follow any rules. I only ask because if you're correct I want to get a new battery. Also, what would I tell HTC to get q replacement? Thanks..
[Nexus One General] DarkDvr:
You know I also read about LiIon batteries quite a bit, and although it is very weird that there is a whole procedure of the "initial charge"...

HTC support guy told me that first charge is very important and has to be done right. He said that you should charge it with a low current charger, a USB, for 16+ hours, best if for 24 hours straight. He said that you can also charge with an AC adapter for 12 hours, if you don't wanna wait so long. He also said that they don't recommend using a fast car charger because it "damages batteries over the long run". Whether phone is on or off shouldn't matter, but they recommend it to be off.

So far I can't confirm or deny it. I'll try it as soon as I get my new battery and report here.
[Nexus One General] vegetaleb:
Customs ROM are the biggest player in terms of battery drainage!

I used CM 5.0.5.3 and 5.0.6 T1 and they both drain 15% of battery in 30 mins (1% every 2 mins) if the screen is light on. Battery passed from 100% to 73% in a couple of hours while Desire and Enom ROMs only used 12% for about 14h.

Enom and Desire will give me about 36h while Cyanogen ROMs give only 15h for the same usage. 2G,100% screen,30 min wifi/day, 5 SMS, couple of calls, background sync off.

I am pretty sure that after some full cycles (1-2 months) it should last 3 days, my old nokia 5800 used to give me 15h juice first 2 weeks but after 3 months it could go up to 2.5 days
[Nexus One General] eboy44:
