Hey everybody. I would like to start a global thread about Mugen 3000 battery REVIEWS. I would like to ask the moderators of this Forum to try and keep this thread tidy as in let's only keep the reviews here, and the general questions in other threads.
Mugen 3000 Review
Ok... I'll go first.
My two Mugens got here 2 days ago. I got a 3000 and a 1500.
Let's focus on the 3000.
- Back cover: GPS flap is a FAKE. No camera protection lens. Shiny, non-rubberized back (I like it better this way) with 4 little legs to keep it floating a bit above the surface (you hear the speaker better).
- Battery: double size, heavier than the standard.
THE REVIEW ITSELF WILL BE A SUMMARY OF PERFORMANCE INDICATORS AND USAGE TOTALS.
I will keep updating this post of mine as I evaluate the performance of this battery.
Keep in mind that I am a BATTERY FREAK and I test batteries to PERFECTION.
If you don't want to read through this long review, you can skip down to the "FAST FORWARD REVIEW" or to the "CONCLUSIONS". See post number 4 in this thread.
================================================================================================================
CHARGE CYCLE 1 - FACTORY DEFAULT
2008-03-26
- Battery came loaded at 63%. After 2 days I'm stuck at 15%. I spoke about 20 minutes on the phone and used the GPS for about 15 minutes. I worked on it about 1 hour adding contacts and such.
- I installed Battery Status for a more correct measurement of the battery but I never saw it disagree with the measurement of the system (in the tray).
- As I said, I am now STUCK at 15%. It was 15% at 16:00 and now it's 23:00 and it's still 15%. Weird. I suppose that it's better than what others described (they needed to reset or remove the battery for the device to realize that there is still some juice in it). We'll see what the following days have to say about this.
2008-03-27
- Battery Status sucks. The program does NOT DETECT CORRECTLY the battery usage, nor does Windows. Today I woke up with my battery at 7%. I soft reseted. Same reading. I shut down Windows and started again. Same 7% reading. I removed battery (with Windows turned on) and put it back again. New reading: 15%. Now after 1 hour I'm at 9% and holding. Almost 3 days of usage with the factory battery. I spoke about 20 more minutes.
- BATTERY DEAD after 2.5 days. Activities total: ~40 minutes phone, ~15 minutes GPS, ~2 hours screen usage (writing / reading). No WiFi, No BlueTooth.
================================================================================================================
CHARGE CYCLE 2 - FIRST FULL CHARGE
2008-03-28
- Full charge this night. 19:00 - 04:00, for a total of 9 hours, just to be sure I respected the instructions for the battery. But it was charged in about 3.5 hours, with about 1.5 hours more than the standard battery. So it charges its capacity pretty fast. Let's see how long it lasts. So far, I'm at 95%. No conversations yet, pretty much no usage. 5% gone in 10 hours, mostly stand by.
- After only 21 hours since the charge, I lost 24% of the battery. I did some text editing for about 30 minutes and about 17 minutes of talk time. I'm pretty disappointed by this relatively "standard" consumption.
2008-03-30
- Two more days passed. I am now at about 64 hours since the charge, so almost 3 days. I used the GPS for about 30 minutes yesterday and talked for about 10 more minutes in total (I don't talk a lot). But the battery is pretty damn low, 28%. I expect it to start dying tomorrow evening. I'll probably remove it and put it back again to see a correct reading.
2008-03-31
- Fourth day approaches its end and I'm stuck at 15%. It appears that my Mugen 3000 has something with this 15% value. It spends a lot of time at 15%. I read that you can stop the device from shutting down when the battery is almost dead by tweaking the registry. I will write the solution here if it proves to be valid. UPDATE: Now at the end of the day, I'm left with 4% juice. I hope there is more under the hood. Today I spoke for about 30 minutes and did no more than 10 minutes of text editing.
2008-04-01
- It's 02:16 (AM) and now it's 94 hours after the full charge. After 5 minutes of talk battery went to 1%. I was too curious about how much there really is left so I removed the battery and put it back. First reading was 44% but it decreased rather fast to 42%. I'll see how it is in the morning. UPDATE: morning, 35%. 10 minutes of talk time so far.
2008-04-02
- At the middle of this day, the Mugen 3000 still holds on. 15% battery after 5.5 days, 10 more minutes of talking. This funny 15% again... been holding already for a few good hours.
- Day end... almost. Battery at 12%. 5 more minutes of talking. So I'm close to 6 days. The Mugen is definitely kicking ass apparently.
2008-04-03
- Only 2% left of my battery now in the morning. Roughtly 6.3 days passed since the charge. I spoke for 20 more minutes.
- BATTERY DEAD after 6.5 days. Activities total: ~102 minutes phone, ~30 minutes GPS, ~40 minutes hours screen usage (writing / reading). No WiFi, No BlueTooth.
================================================================================================================
CHARGE CYCLE 3 - SECOND FULL CHARGE
2008-04-05
- I full-changed it yesterday at about 09 in the AM. Now, after 30 hours (so ~1.3 days) I'm at 69% after 15 minutes of talking and 15 minutes of screen usage (reading / writing). Not such a great number really...
2008-04-06
- After 2.2 days I am at 56%. This is well within the reasonable 20% lost per day I got used with when using the standard battery. I only talked for 9 minutes today so far, and pretty much didn't use the phone for anything else. Since I didn't use the GPS, I find it the ok-ish level of the battery quite explainable. It's good to use the phone like this because I will make a review which is centered on exclusive Phone usage. And right now I'm happy with how things are.
2008-04-07
- Battery @ 31% after 3.2 days and 6 more minutes of talking. I'm satisfied with this so far and expect the battery to last for about 36 more hours until it first dies. This should take me to 5 days. We'll see if I reach the 5 days and how does Windows behave with the registry tweak I made last week. If it auto-shuts down again it sucks. It means I'll have to take the battery out and put it back again every 4 or 5 days, which sucks!
2008-04-08
- Guess what's the battery consumption today. 15%, of course. The famous 15%. It was 15% 12 hours ago, it's the same now. I expect it to start dying really soon though. I talked for 22 more minutes today so far and 4.2 days passed since the full charge. EVENING UPDATE: After 16 more minutes of talk I'm crushed at 7%. However, I will not remove the battery and put it back again to get a real reading. I will wait to see if the registry tweak works or not.
2008-04-09
- After exactly 5 days, I got 40% left. Today I spoke for 15 minutes so far. UPDATE: evening at 5.5 days, battery left: 28% after 11 more minutes of talk.
2008-04-10
- Exactly 6.1 days @ 11%. Pretty disappointing really, considering that I haven't used the GPS at all. But I talked for 51 more minutes, so that is probably what drove the battery down. UPDATE: At 6.5 days I got only 4% left after 10 more minutes of talking.
- BATTERY DEAD after 6.6 days. So this is how the Kaiser behaves as PHONE ONLY. Activities Total: ~155 minutes phone (so 2 hours and 35 minutes), ~20 minutes screen usage (writing / reading). No WiFi, No BlueTooth.
WILL CONTINUE NEXT WEEK WITH A GPS ONLY REVIEW, let's see how this baby performs on a long GPS run.
weekend (from fri 6pm to sun 9pm) - bluetooth on, one hour talking, email checked every 30 min -after 2 days i had 30%
regular day f(from 7am to 6 pm) - - 1 hour, playing games (1 hour), phone 1 hour , email every 30min - batery status 50%
Mugen 3000 Review - CONTINUED
FAST FORWARD REVIEW
CHARGE CYCLE 1 - FACTORY DEFAULT
2008-03-26 - So far I am very happy with the way the battery behaved, especially considering that I use it the first time, no charges yet.
2008-03-27 - 2.5 days is ok for a first-time use of the battery. I'm very pissed off that I can't have accurate battery readings from any program!
CHARGE CYCLE 2 - FIRST FULL CHARGE
2008-03-28 - Pretty disappointed because of fast consumption with relatively nothing done with the phone. It's still the first cycle so I have hope for better at the next cycle. Also, probably the readings from BatteryStatus aren't correct and the power is a bit higher than it says.
2008-03-30 - 28% after some long GPS usage and a bit of talking is reasonably well. I'm waiting for the second full charge to draw more conclusions. Also waiting to see the battery reading after I pull it out at 0% and put it back again.
2008-04-01 - This is not an April's Fool joke. I'm very happy with the Mugen 3000 so far. 4.5 days and it's still holding strong even after GPS and talking.
2008-04-03 - Battery dead after 6.5 days - a very good result considering that I used the GPS (30 minutes) and talked in a normal way (102 minutes), without restraining myself.
CHARGE CYCLE 3 - SECOND FULL CHARGE
2008-04-05 - 31% of gone in 30 hours at the second full charge. Not so great really, considering I haven't spoken so much.
2008-04-07 - Almost 3.5 days and I'm at 30%. Acceptable by any standards, especially considering that the battery is actually at more than 30% if I remove it and put it back again.
2008-04-10 - I expected more bang from the battery since I didn't use the GPS, but I talked quite a bit. The Windows Registry tweak is bull**** apparently, the device still autoshutdowns when reaching 0%. Even if the battery is really at 50%. Very very annoying!!!
2008-04-11 - I used the Kaiser in PHONE ONLY mode for this period. It lasted about 6 days and 16 hours

================================================================================================================
CONCLUSIONS
THE GOOD:
- About 70% to 90% more juice than the standard battery. This baby really has a lot of energy to give and it will last you A LOT.
- Stated capacity (3000 mAh) is pretty much what you get. So Mugen didn't lie about this (too much). Considering that the standard battery is rated at 1350 and this one does not really last twice as much, it's probably less than 3000, but it's still a great performer.
THE BAD:
- Big size, heavy.
- Delivered back cover is a poor match to the phone.
THE TERRIBLE:
- There is NO WAY to read the battery accurately. Let me repeat that. THERE IS NO WAY TO READ THE BATTERY ACCURATELY. This SUCKS!!! The registry tweak I tried does NOT work and Windows simply shuts down when the battery reaches 0%, even though the battery is NOT dead. You need to REMOVE and put the battery back 2 to 4 times in order to really kill it. First time Windows reaches 0%, the battery is actually at 44%. You must TAKE the back cover OUT, then REMOVE the battery, then PUT IT BACK AGAIN and ONLY THEN you get the accurate reading. This is a very big downside of this battery and I suggest you think very well at this before you buy it.
ALL IN ALL:
- I'm happy ::- ). That's because I'm a battery freak and I like to have a very long lasting battery in any phone I own. So far, this is the best battery I had in my entire life in a phone. A battery that lasts almost 7 days after you talk for 2 hours and a half is GREAT. But I don't think I'll use it always. It's very very disturbing having to remove it every few days a couple of times. I think I'm going to keep it for long journeys and use it from time to time so that it doesn't degrade. I will probably use this one for a month than switch to the standard one for another month and so on.
Your way of testing the battery is not accurate because its not a consistant drain from 1 minute to the next. You should start with your OEM battery and use that as the benchmark. To do the test, first fully charge the OEM battery. Turn off the phone radio so you dont get incoming calls or SMS, turn on wifi, run a gps program to activate the GPS, turn on BT, play a video clip and set it on repeat, set the screen brightness to the max. The video clip playing on repeat will prevent the screen from turning off. Doing all this will create a constant and consistant drain on the battery. Now with everything is going, unplug the charger and start the timer. check on the battery level every 10 minutes and record the battery life until the phone shuts off. Once that's done, start the test with 3000mah battery. Doing the test this way will let you know at which point the battery meter becomes inaccurate for the 3000mah. When the test is done you can also calculate the exact battery capacity of the 3000mah. I've done a test like this for my 2800mah battery and it yield 2950mah when it was a week old then 2850mah when it's about 3 months old.
I am still not too happy with the battery of the Galaxy, even though it should be conditioned by now. Nowhere near as good as the iPhone 3Gs, even though the 45nm chip in the galaxy, as well as the AMOLED screen, should be benefitial to battery life.
Maybe a good benchmark would be to see what readings people get at the time of the first "Low Battery" warning. You can see what depleted your battery by going to Settings/About/Phone/Battery Use. To get details, touch the corresponding bar in the graph.
Mine are:
20h 32m 4s since unplugged
Display: 38% (1h 54m)
Cell standby: 24%
Phone idle" 16%
Android OS 10% (CPU usage 50m 4s)
Voice calls: 6% (2m 54s --- WTF?!)
Android System: 4%
K-9 Mail: 2%
Advanced Task Killer: 2%
Those numbers look good to me somehow, I wouldn't expect better battery life after using the display for 2 hours and another 19 hours of standby? Especially as the phone can easily stand by another few hours on the last 15%...
i just got my phone recently, i'll post my results after a few weeks of daily usage.
i do a lot of 3G+, WiFi and SMS, not so much voice call, but regularly enough like two or 3 calls a day
that should be a pretty good test to see how long the battery last from full to like 20% that's when i usually recharge my phone if i don't carry a spare battery with me

It depends on what you compare it to, I guess.
I am comparing it to my old iPhone 3Gs, which would last about 48 hours, usually with considerably longer talk time than the 2m 54s I have on the Galaxy S. How can less than 3 minutes of talk show 6% battery drain?!
As I noted, the Galaxy S's smaller die (45nm) and AMOLED screen should be an advantage over the iPhone 3Gs's older hardware, yet the iPhone lasts markedly longer.
Anyway, I just wanted to see what others are seeing and how long their phones are lasting. It might be interesting to many others, too.
The galaxy S holds considerably longer than the iPhone 3GS. Probably longer than the iPhone 4 as well.
My current stats:
2D 0H 33M 41S Since unplugged
Voice calls: 34% (38m 37s)
Cell Standby: 28%
Phone idle: 19%
Display: 18%
Funny, it doesn't show the time when i played SandStorm and Asphalt.
Oh, and my current battery level: 66%
If i skimp on the battery, i can hold 5 days between charges.

WOW! This is just amazing!
How long was your screen on for only 18%? (I have mine set at the dimmest, but still....)
Do you use email much and if so, how many accounts and often do you have the phone checking it?
Wait, you use tons of WiFi and you're suprised that the phone won't hold too much?
In contrast to the iphones that require you to manually search for a network, android ACTIVELY searches for local open networks and connects to them.
When you're not using WiFi- TURN IT OFF.
If you're talking about cellular internet, that's another thing.
And the display (set to medium-low brightness, the brightest mode where it doesn't BURN MY EYES. Damn this display is bright) registers 1h 27m.

For what it's worth, my WiFi has been off for most of the day.
But, on WiFi discovey, my experience has been the opposite.
On the iPhone 3Gs, I always had WiFi and BT turned on. if I was not connected to WiFi, but WiFi became available, the iPhone would bring up a pop up, asking me if I want to connect to the network.
With te Galaxy S, I can have WiFi Notifications on, but unless I search for a network (usually by turning WiFi off, then back on), it doesn't inform me of available networks.
To boot, even though it remembers both my home and office networks, half the time it does not sign in automatically when I enter the area, but I have to do the off/on thing to get signed on

Well consider yourself lucky! you got an amazing battery from the future or something, because this is not what we are all seeing... I get a decent 30 hours with mine max...
Can you tell us how long is the display time ?
My guess is that I could stay 2 days with my phone if I was never swithcing on the screen.
The thing is that you seems to use your phone like I was using my old nokia 6310 ...
Try to play some music or video and you won't last 5 days or even 2days ... maybe 1 if you are lucky
Basically you have left your phone switch off 2 days and call 38mn and that's all ?? I can't tell you that my old iphone3GS is going to be pretty close in term of performance of battery
given that 1h54 give 38% of 85% for the OP I would say that you have maybe 20mn of display
The battery life of my SGS was terrible for the first few days of use. I don't have the battery usage numbers but the battery would only last for around 20 hours doing: 30-60 min call, 2hour music, 30mins video, 30mins game, and approx. 40mins web surf using mostly wifi.
But after about 5 charging cycles (discharging until battery ran low and the phone eventually turns off, then charging the phone to full), the phone lasts for two whole days with the same usage described above each day!
So I have noticed a significant improvement in battery.
If you haven't gone through the charging cycle and your phone is relatively new, give it a week before you think the battery life is crap
yeah I am still waiting for the improvment
After almost 2 weeks , a dozain of cycle I still don't see it coming ...
I guess I must be using the screen too much ( miminum light) ...
Afert 12h46 I am at 25% with 65% taken by the display , 10% by cell idle, 8% by android , 6% by network idle, 4% by call ...
I have already used the screen 3h14mn
I don't know what you do but on my side I am reading my mails, reading xda, reading some newspaper on the train, watching some video ...
So my crappy battery doens't seem to come from some app draining it ... but just from the display.
So basically nothing I could do except using it less than what I am used to
Display time was 1h 27m
mine last around 10h (display on 4,5h) and thats as low as u can adjust brightness in settings according to gsmarena blog display can last up to 10h...
im using dimmer app now. hope i get 5-6h (display time) with that.
ok i'll play:
10hr:10min since last unplugged.
Battery at 74%
Display: 50% (I leave it on auto brightness)
Cell Standby:19%
Phone Idle: 12%
Bluetooth: 8%
NDrive: 7%
Android System: 2%
I'm happy with that.
I'm easily getting through a 15 hour day with moderate use (my normal usage pattern). this is on a par with my previous Nexus One and iPhone 3G.
BTW, I keep the WiFi on persistently (even when the screen is off) because I heard it draws less juice than the 3G/phone data. (I typically spend a lot of time around the house on WiFi ...)
Battery killer is normally "time without signal", the N1 would average maybe 70% without a signal, the SGS is averaging around 30% without a signal - so based on that perhaps the battery isn't quite as robust as the N1 (which was on Froyo).
Anyway, I have no concerns about my SGS battery based on similar phones and usage patterns. I will be tempted to get an extended battery for it though (I had a Mugen 3200mAh on the N1 and that would give me 2 days under quite heavy usage).

Are you sure about this? I thought I noticed much better battery life when I started to switch wifi off and using 3g instead. I guess it could just be my battery maturing

Keeping the WiFi policy to never disconnect apparently uses less battery than the system thrashing between 3G and non-3G data when sync'ing etc. Typically WiFi will show as 2% battery usage at the end of the cycle.
I base it off my old N1 usage, which I got from here:
http://www.google.com/support/forum/p/android/thread?tid=006a844d7d335a90&hl=en
ok so my phone has been off the charger for ;
5h 23m 17s
I am at 56% battery.
What concerns me is that my display usage is at 56% of my battery usage with just 22m 27s of usage.
now if I do the math that means the display has used 25.76% of a full charge in just over 20 mins of use.
This seems absurd especially for what is supposedly a more efficient display. Do these numbers seem on par or do I have a faulty battery/device?
Has it been conditioned? I know conditioning does nothing to the battery itself, but it does cause the percentages to reflect more accurately.
Also, was it fully charged 5 hours ago when you took it off the charger? If not these numbers are meaningless.
I suggest comparing multiple charge cycles, not one strange instance.

No, I have not conditioned, the phone.
Yes it is coming off of a full charge.
This is the first day I have taken it off the charger for the full day. I have had it connected to computers via USB to install music apps and get it rooted since I got it so I do not have any other cycles to compare it to accurately.
To be honest these batts do not need conditioning, they have no memory effect.
OP Display is nearly always the most. Unless you make long calls (which could make calls the highest) or never use the phone (stand by would be the highest)...
I would be far more concerned if an app or other device function was at the top of the list other than display.
I had initial concerns about the battery when I got this phone. Now that I have settled into a normal usage pattern (few videos, email, web surfing, Facebook, etc.) I get a full day (7am-10pm) out of a charge.
Just use it as you normally would and don't worry too much about the numbers. See how long it lasts and then adjust as needed. You can disable something that you don't need at that particular moment and make a big difference (like turning off Auto-Sync when you don't need to be constantly updated of your friends Facebook status or turning off 3G when you aren't going to be surfing).

The fact that the display was on top is not what is concerning me it is the percentage of the full charge it used that has me worried.
In the total time off the charger at the time of these stats I used 46% of the battery. 56% of the 46% was for the display. That means that in 22 mins my display ate 25% of my full battery, which would equal out to my phone being dead with 1h 20m of screen time assuming no other resource used the battery.
...4 hours of heavy usage (wifi connection and 3g on but idle)
Mid to periodical usage could reach 24h.
6th day of usage....
i think this is mediocre for me. please report your battery performance to compare.
Any tips to improve this?
I can get around 8-10 hours with heavy usage... constant music, etc.. and about 2-3 days with light-medium usage.

Hmm so i guess there is a problem with my device.
Great!, and how am i supposed to explain this to the service?
I get about 12 to 15 hours of heavy usage via web, text, and email. If i watch video it's less but I am pretty happy with the battery thus far.
--Sent from Samsung Tab
I can only get around 7 hours of use.
I have a problem that if i even dont use it, the battery still drain. I got it full charged and theb unplug it. About 8 hours later, it went down to 50%.
Is there any problem with my device?

same here. i don't know how you guys are getting so much better battery life. i can barely last a day and i don't use it all that much. maybe 2-3 hrs of surfing the web over wifi (not even 3g). i even used setcpu to underclock to 200Mhz when screen is off.
Maybe it has something to do with the very first charge.
When i unboxed the battery was fully charged so i drained it and had it charged for 8 hours. maybe it needed to be charged prior first usage.

Is that 12-15 hours with the screen on? Because that's much more than I'm seeing.
I've done a few measurements just to get an idea of the battery life. They are just extrapolations based on a few hours of runtime for each so they are by no means exact, but my impression is that they give a decent view of real values nonetheless. The battery percentage indicator does not seem to be terribly non-linear.
Video playing (SD quality) with full brightness: 5.5 hours
Video playing (SD quality) with lowest brightness: 9.5 hours
Idle at homescreen with full brightness: 6 hours
Idle at homescreen with half brightness: 9 hours
Idle at homescreen with lowest brightness: 12 hours
Music playing in headphones (screen off): 90 hours
Can't believe how lazy reviewers seem to be, I haven't read a single one where they have properly measured battery life for things like playing movies or reading an ebook. It's all just subjective feelings (which are obviously very unreliable).
All in all I am pretty pleased with the battery life (but I've just had it for a few days). I especially like the fact that it's basically a normal Android phone just with a giant screen and battery. This obviously means that standby and music playing times are going to be excellent.
Edit: Those of you who think you're seeing bad battery life, what does the battery use thingy in settings say? Or is that not a good tool?
I read a post somewhere where the OP was getting horrible battery life and found out that the Gallery app was draining the battery.
The OP in that thread said even exiting the app did not kill it, and it kept draining the battery.
Perhaps you can look into this more. I never use the gallery app so maybe why this is why i get decent battery life?
Edit to add:
Here is the thread

If it's this post you're referring to it's by me . The Gallery application shows up under battery use though, so I'm pretty sure that's not it.
Are you sure it's really as much as 12-15 hours with the screen always on? If it were 9-10 hours with brightness at half it would around what I'm seeing I guess, but 12-15 is quite a lot more. Not that I'm disappointed, but if better is possible better is what I want

No not 12-15 hours with the screen always on.... I get 12-15 total... Screen on for usage, off for a while, back on to email and SMS ect...
Ah ok, then there's no discrepancy .
I got 10 hours from full to complete off. I was using it to watch streaming movies on 3g
for a couple of hours and then watch a movie off of the sd card and an episode of supernatural.
After that its just web and ebook reading. Its pretty good. Almost the same as my ipad.
I got a total of around 14 hrs plus with wifi and edge on, screen brightness at 20%, around 7 hrs of standby while i was asleep at night, with 4 hrs of heavy surfing, youtube etc. . . No calls though, only some sms and always on IM with nimbuzz logged in.
What i am seeing is with heavy usage i.e. Multiple apps running, wifi and edge on, i get anywhere between 5-7 hrs of battery life which i think is fair enough for a device this size which am constantly fiddling with.

Can someone please post,
Using the supplied mains charger, how long does it take to fully re-charge a drained Galaxy Tab?
As it is a large battery what sort of charging times to expect?
(This is while NOT using the device).

I've not used mine for that long, but the Battery Left app(which I found to be quite accurate on my N1) shows that for MY usage, I'll get about 25hrs.
I've got the auto dim turned off, and brightness at max. I mainly use mine for checking emails, txting, and a few games.
Nothing heavy.
I'd recomend the Battery Left app to you guys looking to find out your battery life. You DO have to "train" it though, which requires a 100%-0% run for you.
Guys,
does.anyone know, do we need to cycle the battery to give it the best performance?
Example, charge up the unit, then drain it completely and recharge it again? Like in the old days.
mine hasnt gone down much. I have it unplugged at 6am and at 4pm i still have about 75-80% batt left.
This is with about approx. 2 hrs of talk and 30mins of data usage and voice calls paired to my BT headset. My screen brightness is set to 40%

I once got up to 20 hours of moderate usage. But with heavy usage I get about 12 hours or more. I lose about 7% when watching an episode using flash....kinda sucks but I watch a lot of anime online. But I use this as my main phone too. Its replaced my nexus completely. though it was nice with my nexus cuz I could swap batteries. This is how I condition my battery. I let it get to about 2-5% then I recharge it. I don't let it get to zero cuz I heard you can damage the cell. sometimes I charge it to about 20% then I unplug it and drain it to 5% then back up to full. I just kinda switch it up. At first I was getting horrible battery life but ever since I started conditioning it this way I get great results.

I have been letting a couple of days go by to see how the battery is and I have got to say that I am highly not impressed. I love the phone and even like Blur but the battery is really a let down. I know that the first day or so that I use the phone heavily because of course.. ITS NEW. But today I have been real busy at work and have maybe text a few people, made 2 calls, and looked up a number using google maps and my battery is now down to 60%. In battery manager, it says 5h 2m 25s since unplugged which would be me taking the phone off the charger this morning and heading to work. Other stats are:
Display 35% 29m 52s
Phone Idle 26% 4h 32m 47s
Voice Calls 24% 6m 45s
Cell Standby 11% 5h 4m 5s
Wi-Fi 6% 1h 51m 56s
From looking at these battery stats and usage, does it even seem correct to be at 60% battery? This is at the least very minimal usage for a phone.
Yet another battery thread... One thing before people start complaining: don't estimate battery life based on battery gauge! Complain once the battery is dead and you HAVE to charge. That's the real mileage you'll get from your battery (and give it a few days to calibrate). The gauge is not a good indicator.
I am a new Atrix user too and so far the battery life is 12hrs or less. Maybe that is not impressive. Coming from the N1, its alright in my book.
I do want to say to everyone complaining about the battery life:
It can take a week or more for the battery to settle into the routine and perform to its maximum ability. Lets start the conversation again later next week on where our battery is at.
Yesterday I got 13 hrs between unplugging the phone, and getting the 15% warning. Not all that bad. Not great, but definitely could be worse.
mine has yet to drop below 30% and im pretty much browsing the web and texting all day. I dont care what kind of phone you have but making voice calls and playing games/watching videos kills battery with a quickness no matter how big a battery you have. . The atrix in my personal usage is just as good as my ip4 was.
the atrix was very good on battery life compare to other android phones i've had
Have the Atrix and Epic 4G and the Atrix lasts easily twice as long as the Epic.
I have to keep he Epic pluged in for my hour comute with pandora, just to make sure I have enough battery to make it for the trip home. Normal usage during the day with brightness all the way down, wifi off, BT off, sync On.
Had the Atrix today (day one after full night charge, unpluged at 6:30a), kept BT On, WiFi On, Brightness 100%, Sync On, Exchange Sync On, Auto off/standby set to 15 minutes, Pandora on via BT for my hour trip (unpluged), forest Live Background, Weather Widget etc.,downloaded everyting I could think of/find, constant e-mail, and constant "whatsApp" till noon (lunch), wache YouTube Videos for my whole hour lunch (still full bright mind you). Created 10 minute Install Video with 720p for work, then uploaded via WiFi, not USB. More Texing, Calls and Downloads. .... FINALLY haed to plug it in at 2:30p, with 5% battery left, I think I could have made it till 3 for sure.
That's a full 8 hours of NonStop Use of everything. I expect to get Morning-Night life from normal usage.
Final word. Test it first. I did and it's Great, not just good. The receiving end of all my texts and e-mail blasting and video look ups has an iPhone. He had to charge his at 2:30 too, but has his iPhone set to max battery save (brightness 15%, wifi off, sync off, etc.) But was using as intensly as I was
... okay I'm done ...

Well I must have a bad battery or something then because I am not doing nearly half the stuff that you are doing and am now at 30%. Is there any special charging methods or anything that I should try to squeeze out a few more hours on this puppy?

may be you have several internet connected background service running behind the scene?
My attitude towards the battery is a mixed bag.
1) PRO: It blows away the battery for the Eris (which I'm coming from)
2) CON: As these phones come to be computers with phone capability, it's really time for manufacturers to try their hardest for better batteries. I'd eagerly accept a phone twice as thick as this one if it meant double the battery life.
I find mine is only good for 10 hours (much less with heavy usage, but low calling time). I expected more.

I really call bull on this.
Coming from the world of Airsoft, I'm no stranger to battery performance.
Most of these performance myths are hold overs from the Ni-Cad days and don't apply to modern batteries.
Call Bull all you want. But it was true to the N1 and so far its been true to my battery. It does not last the first few days and gets better after a few charge cycles.
Frankly, everyone believes whatever they want on batteries. I for one take it as a user by user experience. I watch my battery life a lot, but I also like to have Google Reader and Google Listen syncing.
I'm at 30% right now and 12 hours unplugged. What I wouldcall moderate use. Its not as good as my captivate on custom rom / kernel but its far from bad enough.for me to complain about

Andriod sucks the battery, bigger battery on Atrix didn't help much. Google need to optimize the OS for better battery management. I am disappointed coming from Samsung Focus & iPhone 4, both have superior battery life. BTW, I am on Day#4, conditioning the battery didn't help any so far..
Within Range
Looking at all the comments - I would say the Atrix is within range -- I knew when I saw the 1950 mAh (or whatever the exact spec) that the tegra processor must really be a power hog -- the new processor, along with the huge screen is going to draw a lot of power. Comparing to other phones with single core processors and screens even 20% smaller is not reasonable.
Definitely a good point... going to be interesting to see how well other dual core are going to hold up. That will be a better comparison.
Is that battery really a 1930mAH? The size looks like any 1500mAH battery isn't it?
I managed to get close to 16 hours of 'normal' use, meaning I wasn't trying to drain it, nor was I trying to conserve battery. I took the phone off the charger at 3pm and made it all the way to 2pm the following day with about 20% left. That's 23 hours, but I subtracted out the time the phone was on while I was asleep, 8 hours (nighttime mode).
Hmm hearing all these replies i believe i have a defective battery. I unplugged mine today at 5:15AM and now it's 2:18PM and it's just gave me the 15% beep. I've sent about 25 texts and played some words with friends. I've got watchdog installed and no apps seem to be out of control. I'm wondering if a factory reset would fix the issue or if i should return it.

try going to your dialer and entering *#*#INFO#*#*
Look under the battery usage and check the different items. Is anything using a significant amount? it could be a rogue app.
I will say MotoBlur has a lot running in the background. About twice as much as vanilla android.
I have turned most of this off and I do know that is helping my battery life.
