As many of the launch phones are fairly similar in terms of specs, I am wondering if battery life might actually be a larger factor in my decision to buy a WP7 device.
For example, my first instinct would be the HD7, however with the largest screen will it likely eat through the battery at a rate of knots, or is the lack of true multitasking and microsofts minimun specifications likely to help ensure the battery life exceeds many existing smart phones, such as my Nexus one (which usually only lasts a day for me).
I tend to take spec sheets with a pinch of salt, as they often don't match real world experiences, but would love to hear from any one that has had a chance to test a WP7 device themselves.
My rule of thumb is that the larger the screen, the more battery it uses since the display it's the primary drain.
However, since the HD7 is the thinnest launch phone, it could be a good candidate for an extended battery that wouldn't make it too bulky for everyday use.
The problem there, is a WP7 to me is desireable specifically because of the UI and general asthetics over my existing Android (which I feel is actually superior to WP7 in terms of functionality). Clamping a giant battery to the back would ruin that effect for me.
I'm struggling to find much comparitive information on each WP7 battery size. Any else able to find a list? I've seen a few websites that I would not normally trust indicate the HD7 only has a 1200mAh battery, which is one of the smallest of the WP7s. Surely that would be a bit of a weak chinc in the HD7s armour?
The hd7 has a smaller bathe then the Mozart, from what I see the omnia7 is the best as its soles screen and the biggest battery I have seen so far

Dell Venue pro is 3 hours or up to 7 hours talk time?
They have 2 different info from microsoft websites.
http://www.microsoft.com/windowsphone/en-us/buy/7/phones.aspx#detail=1568
The same for Samsung Focus. Because of its thin profile I am willing to believe 3 hrs of talk time over 7, which seems exaggerated.
Focus/Omnia7 are listed as 3hrs talk time? Sounds strange. I heard it had a 1500 mAh battery - coupled with the more efficient S-AMOLED screen it should have more...
HTC 7 Trophy - has a Removable and Rechargeable Lithium ion or Lithium-polymer battery, 1300 mAh.
HTC 7 Surround - has a Removable and Rechargeable Lithium ion or Lithium-polymer battery, 1230 mAh.
HTC 7 Mozart - has a Removable and Rechargeable Lithium ion or Lithium-polymer battery, 1300 mAh.
HTC HD7 has a - Removable and Rechargeable Lithium ion or Lithium-polymer battery, 1230 mAh. Small battery for such a large screen.
Samsung Omnia 7 / Samsung Focus Has a Li-ion, a 1500 mAh. (Only 8GB of storage)
Dell Venue Pro is listed as up to 7hrs talk time / 14 days standby. It's got a decent size battery and the AMOLED screen which likely helps cut down on the power consumption.
I'd wager a guess that the S-AMOLED and AMOLED phones will have the longest battery lives, so long as the OEMs don't gimp the battery inside.

Samsung's site says:
Up to 300 Hours Standby Time
Up to 6.5 Hours Talk Time
Just for reference, for the iPhone4 Apple claims:
Talk time:
Up to 7 hours on 3G
Up to 14 hours on 2G
Standby time: Up to 300 hours
The Samsungs, when using dark themes. 1500mah battery with AMOLED will last you the longest. LG with 1500mah when using light themes. Power draw of the rest of the electronics should be more or less the same, since the platforms are almost identical.
Was about to say something similar. AMOLED should be really good with WP7 as it's quite a dark OS. Those screens take a tiny amount of power to display black (and loads to display white). Combined with a 1500mAh battery and you'd expect the Samsung to do the best.
From what I can see the LG phones have the longest talk time by far (10hrs).
I also thought the AMOLED screens were supposed to be great on power consumption but Im not so sure that works in real life...the samsung phones that I can see are all rated for 3 hours which is really too little...

Omnia 7 battery life...
Talk time: 2G / 520Min, 3G / 370Min
Standby: 2G / 390hrs, 3G / 330hrs
http://www.samsung.com/uk/news/newsRead.do?news_seq=20829&gltype=localnews
I was thinking the Omnia 7 was going to be the phone to get with its 4 inch Super Amoled screen and 1500 mAh battery, But 8GB memory is just to small.
Why no 16GB version Samsung???
Well, I have never had a problem with battery life, on my Vibrant I had a pretty decent run with some sporadic use. With my G2 I had an alright run, but it had an underclocked processor so most likely that helped with the battery life... I don't know, Android has "multi-tasking" and that can hog up the battery a lot. So maybe it might hold up alright on the HD7, regardless I always carry a USB cable in my car, and a car USB adapter, just in case.

You make a good point...2G vs 3G...on MS site they show the 3G phone times for Samsung it seems but I wonder where the 10 hours come from for the LG...2G or 3G...believe it or not 6 hours(370min) is not enough for me...I know that is best case and with other things running on a smartphone it will be more like 4-5 hours...
i like win 7
Samsung's phone will most likely last the longest as it has quite a good battery and the screen uses less power than other screens.
Just want to share some early impressions of Anker 2500mAh battery for the Note.
I brought this on Amazon UK for £10, which is half the cost of the cheapest stock battery I can find from trusted online shops, the Anker seems few grams heavier than the stock battery.
I have used the Anker in the Note for two weeks now and decided to do a control test against the 4 months old stock battery.
The Note was set to play 720P version of “The six sense” on desktop version of YouTube using Boat browser at full brightness, with the sound at 50% output to a pair of headphones.
The YouTube page was refreshed every 1:30 hrs to restart the movie, and battery usage recorded after the 5% low battery warning popped up.
As you can see the Anker lasted 1 hr longer than the stock battery in the test. It would have been better if I had a newly conditioned stock battery to compare against the Anker. Still it shows the Anker advertised 2500mAh capacity is not too far off.
I’m going to continuing to use the Anker as my main battery and the stock as backup. I also had an Anker battery in my HTC Sensation for 3 months and was very pleased with the battery life, so I think it should stand up pretty well for long term daily use.
So if you don’t want to spend £20 on a stock battery, the Anker is a very good alternative. It is few £ more expensive than some generic batteries on eBay, but Anker has good reputation with their products, just check out the long thread in HTC Sensation accessories section.
Thanks for the compare. 4 hours screen time for stock battery is kind of disappointing.
I actually own one and it fairs well as a spare for prolonged usages.
I owned two spares for my Galaxy S2, also. So in a nutshell, quality and performance of the Anker brand has been consistently excellent.
For $12, it's worth the purchase. :thumbup:

To be fair, the test was designed to stress the battery to the maximum under controlled condition.
The Note was playing a 720p Flash video with full screen brightness. The movie also has very little black background, so the OLED’s power efficiency is minimised.
I also had the phone’s cell radio enable and CPU scaling set to “on demand” so the battery drains even quicker.
Under those conditions, 4 hrs of usage for a 4 months old phone battery is not too bad, a new stock battery would probably last around the same or more than the Anker did.
I've no problem using the Note all day long with the stock battery with Juice Defender to auto manage my data connection.
Agree, you were over-stressing the battery, but Engagdet got over 9 hours looping a video at 50% brightness (still overkill IMHO).
Also, in my experience, Juice Defender has always given me less battery life when enabled. I got about 30 mins more display time and 2 hours of overall time with Juice Defender off vs. on.

I'm confident that they were not looping a flash video, but a locally hosted video file. The OPs test.stresses the device much more as flash video consumes a lot of battery power to play, especially as he was streaming the video, and the screen consumes a large amount of power at full brightness.
For what it's worth, I bought one of these on this thread's recommendation, and have not been disappointed.
I purchased one of these for my S2, it was dirt cheap. Absolutely brilliant battery and it seems Anker have done it again, highly recommended and I may well purchase one of these for my Note soon.
Thanks for the battery recommendation!
What charger would you all recommend to go with this battery?
It has been a month now since using the Anker as daily battery, so I decided to run the same test again. As you can see, there is no difference compared to the test I did earlier, so it seems to be holding the charge. I'll do the same test again after 2 months to see what the difference is.

There is no way the Note battery can last 9 hrs, I got a new ipad on the weekend and was using the stop watch on the Note to time how long a full charge take. After 6 hrs and 30 mins, the Note battery was around 18%, the Note screen was at minimum brightness most of the time.
So I call BS to Engagdet test on the Note, even though their battery tests are accurate most of the time.
anyone know where to buy?

I got the Samsung Battery Charger Stand, it charges via the same type of USB port on the Note. I use my Note in Desk Clock mod during the night so the stand coming handy, I can position the Note horizontally so it can be connected to a wall charger.
Link to Amazon
thanks for the review and the opinions guys! currently searching for a good yet price worthy battery to buy!
Attached are my stats with the first full charge cycle with this battery. Needless to say, I'm very pleased. Awesome value!
Thanks for the battery recommendation!
but i hope that will release a galaxy note battery with built in NFC chip...
Just bought two of them for 20 bucks, I saw the review decided to give them a try. Ill report back about quality but I hope they are as good as I've head.

I bought Juice Defender Ultimate & it was useless for me. My battery ran out faster with Juice Defender than without. Not using any battery saver app anymore.
how about Nomax?
anyone hv any comment
i saw in ebay its look good but im not sure.
I'm noticing that my phone tends to drop from 100 to 90 pretty quickly, but after that sips battery. Anyone else notice this? I got to 12 hours yesterday and still had about 50% left.

I wonder if it is something that your phone is doing right after you unplug it (maybe you can see it in the battery status or in Better Battery Stats) or if it is a battery issue.
I have a noticed a similar behavior but it is only when I use a non Samsung battery.
I have three batteries other than the one that came with the phone. I have one that is labeled as a Samsung that I bought on Ebay (it is a fake) and I have two Hyperion (that I bought on Amazon).
With the Hyperion batteries I have noticed that the battery percentage displayed by the phone will drop off very quickly as soon as I unplug the phone. After that the will last all day and seem to last even longer than the original Samsung battery. I suspect that it may because the cells are slightly different than the ones in the Samsung pack. I notices that the Samsung (original) battery is marked as 3.8V 2100mAh while the Hyperion is 3.7V 2200mAh. I am not sure if the voltage difference is significant but they do behave differently.
The fake Samsung battery from Ebay is a piece of crap and I will not use it anymore.
I mean it's not dropping instantly, it just seems to get to 90 faster than it drops after that. I'm still getting good battery life, it's just OCD that makes me annoyed by that initial drop.
Sent from my SPH-L710 using Tapatalk 2
That is kind of what I am seeing with the Hyperion batteries. It will drop to 97% within a couple of minutes even if the screen is off and I am not using the phone. It will get to 90% within an hour or so. After that the battery performs well.
Mine will actually stay at 100 for a while, then go from 99 to 90 pretty quickly. I'm using the stock battery.

The overcharge prevention circuit in the battery stops accepting a charge at 100% and allows the charge to decrease to around 90% before accepting a new charge. Even tho it shows 100% its actually somewhere between 90 and 100 depending on how long it sat fully charged before being unplugged. This extends the life of the battery and prevents damage from overcharging. Samsung doesn't fully disable the charge but doesn't allow a full trickle either it allows a very small charge to pass thru to try and keep it as close to 100 without overcharging, but background processes can drain the battery faster than the trickle can replace it

SBC is a form of trickle charging that puts out a full trickle which can keep up with background processes draining the battery. However, if you charge overnight while you sleep it is overcharging the battery for about 4hrs if you sleep an avg of 8hrs which isn't good for the life of the battery over time. The overcharge circuit is to aid in mitigating cell damage inside the battery. Li-Ion + heat isn't a healthy mix. It's like smoking a pack of cigarettes everyday and expecting to live to be 100. There's a trade off involved. The best way to get a full charge is to unplug when u get up let it drop a percent or 2 then plug it in while you get ready and let it.go back to 100%. SBC won't kill your battery over night but after a year or so don't expect it to hold a charge as long as it did when it was new.

one of my friends said to me not to buy thoese batteries. he says thoese high mAh'ed batteries will loose their power soon. is it real ? well tbh all batteries loosing their power as the time passes... ah.. this battery thing is a big problem for g wonder.
my friend bought a galaxy trend plus few weeks ago. he showed me his battery graph. i coudnt belive. it has passed 15 hrs since he plugged off from charger and it has still %98 battery. the graphic was like a mountatin road. i mean like this /\/\/\ it is something like battery charging itself back. same thing happens to me when my battery is nearly under 10 percent. for example if it is 6 becomes 7 and 8... slowly. strange

This is because of the battery indicator on phones. Although it detects how much juice we have left in our batteries, it detect em' very inaccurately. Once, my phone was draining battery fast till its battery was at 4%, i reboot it and shockingly gotten 80% of juice left.
Saintsoh also mentions to reboot your phone many times cos its like you're refreshing ur phone. It'll also give a slightly better reading after that
Via the Internet
Hope this site is still active for the S3!
I recently signed up for a Pay As You Go Plan as a backup phone number using my old Verizon S3 which had been sitting around for 3 years without use. I noticed that the battery (original 2100mAh that came with the phone) has bloated a bit and it holds charge for less than a week even without any usage. I purchased an OEM battery from eBay but that lasted even less between charges! I would like a battery that would hold its charge for over a week before requiring a recharge. I would like to avoid having to have two batteries and swap them during the week.
I looked up the suggestions on this site but many of them (Hyperion, Anker, ZeroLemon) are no longer available. I found only the following batteries on eBay.
4800mAh High Capacity Battery + Blue Door For Samsung Galaxy S3 SIII i9300
X Power 4800mAh High Capacity Battery + Blue Door - Samsung Galaxy S3 SIII i9300
EXTENDED 4300mAh Battery + Cover for Samsung Galaxy S3 SIII i9300 T999 L710 i535
4300mAh Extended Battery for Samsung Galaxy S3 Blue Cover Dock Charger
Can anyone recommend any of the above or any other battery? I would like it to last at least a week between recharges. Also, I would prefer not to have to pay more than $20 for it if possible. I am in the U.S.

No, I have not used either one, but they both have decent reviews.
Thanks StoneyJSG! I had given up since not receiving any reply for two months and was pleasantly surprised seeing your response.
The battery at Gorilla Gadgets looks interesting. I will check it out.
Purchased the Gorilla Gadgets battery from WalMart (here).
Received a black back cover instead of blue one. Otherwise, the battery appears to hold significantly more charge than my original battery. After over 4 days after charging, I still have 75% charge left. This is with no use except for turning it on once or twice a day to look for missed calls/texts. It will easily surpass the 7-days I needed so I can charge it once every week or so!
Thanks again OP!:good:
P.S.: Gorilla Gadgets sent a blue battery cover for free!
Battery held charge for 14+ days before reaching 5% level. Very satisfied so far. Will update post if I see anything different over the next few recharges.
Thanks again StoneyJSG and Gorilla Gadgets!:good:
