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.
*Build Quality/Performance*
Let me go ahead and mention that this thing is the biggest and baddest of all external battery packs! Rated at 32000 is a true juggernaut. This is meant for warriors on the go. It has ability to charge any laptop laptop, tablet, phone and everything under the sun. It’s about the size of my Nexus 7 (7 inch tablet) in length and width but undoubtedly thicker.
A three toned appearance in silver faux metal, glossy black and glossy white.
It definitely feels solid in the hand with nothing bending or creaking. It has a nice little lcd screen telling you the exact percentage of charge left and the output voltage. The voltage is more specifically if you’re charging a laptop that has very specific needs. 9V/12V/16V/19V/20V are all selectable output voltages. It pretty much has all the connectors for ever type of laptop you can think of, 10 in total.
It also has 2 usb ports, a 1 amp and a 2.1 amp output. To connect phones, tablets, cameras, portable gaming systems etc etc.
The one thing I never liked about smaller battery packs is that you'd still end up charging them a couple times a week.
I was able to charge my Nexus 7 and Nexus 5 at the same time with no problems. I also charged many different combinations of phones and tablets comprising of Ipad 4 Retina, Nexus 7, Iphone 5, Nexus 5, Samsung Galaxy s2, S3 and Ipad mini.
It take 2 whole days to pretty much go from 100% to 0% charging various devices.
Total MAH actually charged via devices = 24297
24297/32000 = 76% efficiency of the battery to charge other devices.
Basically 76% of 32000 is actually useable. Which is a really good % compared to other external battery packs.
Also, it was able to charge my Lenovo Y510p laptop no problem but I didn’t use it in the testing as I mostly used it when I was out and about.
*Conclusion*
If you’re looking for something that small and portable to use around the city this probably isn’t for you but if you fly all across the country and don’t want to worry about any of your devices running out of juice or having to find a wall socket then this would be. It is a monster of a battery pack meant to do serious work. For the price, having the ability to charge me laptop and every other device is a no brainer. Especially not having to worry if the battery is charged all the time.

Cheers, how much is it and where can we buy it from? Uk if poss...
does anyone know if the battery is removable on this device?
You can't.
Sent from my SM-P905 using XDA Premium 4 mobile app
Have you ever opened a tablet? The battery uses by far the most space, it is flat and pretty large. Even if the battery was changeable you would have to lug a huge flat battery with you. You are better of buying an external battery pack. I have 15000 mAh anker battery pack which brings me through a full day of continuous usage. A battery pack is transportable the internal battery used in tablets is not, just because of its dimensions. If you meant if the battery is replacable, on samsung devices you can open up the back panel with some tools and change the battery, it has a connector and is easy to replace once you have opened the device.
I't's replaceable without some effort
Dear guy,
I have discovered this video from youtube. If anyone like me, find the battery is "to old (i.e. contains less power soon or latter)" in the near future, you can see whether you can fix this for yourself. In the video, it seems quite easy to "teardown" the SM-P60X.
Hope that helps all of you,
KELVIN
As the title suggest, its possible to put Note 8 battery in our beloved Note 7 the capacity is a bit smaller (200 mah less, but still 100 mah more than what gimped Note FE version sports) . Its inspired by similar thread by Mr.Ultimate, he did some testing and modification with s7 battery.
I did some research for compatible batteries:
donce1991 said:
got my hands on some batteries, so I can post some dimensions (width, cos its the most important one and capacity), so far those are the ones who are not compatible (I got original ones, fake and copies can and most of the time will be a a different size):
s6 46mm 2550 mah
s6 edge 44mm 2600 mah
s6 edge+ 44mm 3000 mah
s7 edge 42mm 3600 mah
s7 Active 40mm 4000 mah
s8 40mm 3000 mah
s8+ 46mm 3500 mah
note edge 40,6mm 3000 mah
note4 41.4mm 3200 mah
note5 42mm 3000 mah
so far only these are compatible:
s7 39mm 3000 mah
note8 39mm 3300 mah
but still there are about 1 mm of width needed (original battery is almost less than 38mm) so you have to either take the tape off the battery and fold its sides or better remove that frame part between battery and motherboard, so because of the size, I did the mechanical modification and put Note 8 battery in my Note 7.

Manufacturers codes for Samsung S7 battery is GH43-04574C, for Note 8 its GH82-15090A, its just a shame they used much wider batteries in S8, S9 and plus models, but they might use narrower battery in upcoming Note 9, so upgrading and getting bigger battery might not be out of question
As far as I could tell the Note 8 battery is the most promising for its size and device line (still Samsung Note series, just newer) so maybe better compatibility too and so I went with it
For everyone who would like to repeat this process, of course first you need to open your phone. You can look at ifixit.com note7 teardown or youtube for how to open it up and general guidance before you try anything, especially if its your first time opening a glued phone.
You need to remove at least the motherboard and the old battery for this modification (better yet, to remove all the components - easier to clean after), then you have to cut that frame part colored in red between battery and motherboard, cos original S7 or Note 8 battery is a tiny bit wider and removing that part gives fit just enough space to either one. You can use the dremel or any other similar tool to grind it off (I don't recommend cutting it, cos it might stress the frame too much and break the screen, but its just my preference). Then I used some black paint to mask exposed parts like here and here (for a closer look), optional, but I think its safer that way.
Now then new battery can fit comfy inside, had to bend the flex cable for reference, cos there enough space, also the new battery already comes with its own adhesive strips, if you get a diff battery, you can buy some 3M adhesive or similar double sided tape. What's left now is to remove the controller from the new battery and solder on the controller from the old battery.
Because batteries don't like heat the best bet would be to use spot welder, like they do in factories, but that's a bit on the expensive side (unless you do other electronics projects and happen to have one or made DIY one and even then the size of the tabs would be challenge too). So more realistic option would be to use soldering iron and some solder with flux, but because battery tabs are aluminum just any soldering flux won't work, because solder just wont stick properly and wont make permanent connection, which can add some resistance or even make a loose connection over time. So you must use specific soldering flux which eats into battery tabs and makes perfect connection. I tried few generic flux types I had on hand and basically ruined the endings of the tabs cos the solder just wouldn't stick to it, so I got some cheap zinc flux from local shop and it worked perfectly even using the same solder. After that you can use isopropyl alcohol to remove the remaining flux off the tabs, just don't short the battery.
Some pointers:
Try to get original battery, fake or low quality crap from ebay wont cut it, not only because of lower capacity (there are no chinesium batteries who can beat Samsung in battery capacity in same size, period) but because of quick charging too (you shouldn't risk fixing Samsung fire hazard with your own DIY hazard).
MUST use battery controller from original battery, using other controller can and will produce some problems, the controller itself doesn't measure capacity, only voltage, so diff capacity doesn't matter, but diff controller wont "talk" with the phone properly, only using Note 7 controller the phone can charge from 0 to 100% and give full incremental readings and battery charging application actually see the right capacity (about 3300 mahs in Note 8 battery case).
Solder the old Note 7 battery controller directly to new battery tabs, using wires, extensions, etc could add some resistance to connection and you won't get correct battery readings or end up with crappy or slower charging or worse.
I did tried using Note 8 battery without Note 7 controller, even had to make some DIY connectors. The Note 8 battery connector is the same as the one on Note 7 motherboard so even not taking into account different flex cable length and form, you cant just psychically plug Note 8 battery to Note 7 motherboard. So I took some connectors from dead Samsung S6 motherboards and frankensteined them to flex cable and with some wires I got this and this, thus I could use new the battery without any disassembly or soldering directly (to the battery) just by plugin it with DIY inter connector. It looked all good and tidy inside, that outlined area is there the old flex cable was routed (for reference then closing the phone), but it didn't worked properly, I got crappy indication when charging/discharging, the phone couldn't properly detect exact percentage when charging, like, it could sit on 5% for half an hour, when jumps straight to about 80%, or go gradually to about 30-35 and jump to about 70-80 and just sit there and if rebooted it would go to 99% and so on. Also the official wireless battery cover didn't worked properly too.
As for software side I did jumped for a few weeks through diff roms to find the best one for me (Marshmallow based ones works great, but for some you need diff kernel because of charging cap, while Nougat roms are newer, but can be less stable, lack iris support and official covers, that you can get really cheaply, doesn't work too). So I ended up using original Note 7 Marshmallow rom (the one with 30% charging cap) and hydra kernel version 1.3.5, had to extract this version from hydra rom , cos you can separately download only 1.3 version (from here), recovery twrp 3.1, rooted with SuperSU 2.82 and with Europe Multi-CSC selection from CSC Selection. Of course I still get that nagging notification every time I charge the phone, but its a small nuisance. Also removed some bloatware with No Bloat Free app to make it snappier.
So far it works great for me as everyday driver. I charge the the phone on average every two days, it takes less than two hours on average to charge (I try not to use fast charging much) and its holding about same or even better than my old rooted Note 4 (n910c) with new battery. SOT is great (like more than half a day on wifi playing youtube, ect), (SOT time, usage, by apps. After using the phone for a few months I get average charging/discharging and usage time like this). Of course the system or other apps won't detect the exact capacity because they take the capacity from the model information not from measurements, so because the model is n930f, the system reports original hard coded Note 7 capacity of 3500 mah, but because I used BuildProp Editor app to change the model to n935f other apps shows 3200 mah (like it should for Note FE model), while only battery measuring apps like AccuBattery report actual 3300 mah (estimated capacity is measured, designed capacity can be changed manually, by default it would show 3200 mah) capacity.

Perfect, you are amazing man
I liked your ridh illustration i already do modification with s7 battery and thing good
But i found that charging speed is low however im using original charger and cable so
what do you think the problem is ??
And do you think that note 8 battery is far better than s7 battery ??
Thanks in advance

glad to hear somebody founds it interesting and that there are more note7 fans
your slow charging speed could be from using low quality battery, most batteries you can find on ebay are fake ones (crappy charging circuit or lower quality and lower capacity or both), also depends on the rom and especially on the kernel you using, i found the hydra kernel being the best with charging speeds. As for note8 battery, its better mostly because its newer and bigger in capacity compared to s7 (3000 vs 3300 mah) and because of the almost identical price i could get them so because if you use real original s7 or note8 battery you have to modify the internal frame for either one to fit why not go with bigger one

Regarding to charge speed i tried (Note FE ROM) and (Hydra rom), charge speed still the same
Do you think that problem related to quality of soldering paste !!
BTW you saved my ass when you mentioned note 8 battery
i was about buying new note FE battery with 92 $ ,, and now i can buy original note 8 battery with 24 $
Anyway i atill want a tip how to make note 8 battery thiner without do modification to Note 7 frame ??

soldering shouldn't make a big diff, basically if its works you probably soldered it correctly, otherwise you would have some fire on your hands as for note8 battery its thin enough, if you mean width, then you could try to wiggle it in, i didn't took a chance and made a modification, cos even if you manage to put it in inside it would be way more crammed than the original battery was, so a bit dangerous, as for charging, mine takes less than two hours (i try not to use fast charging much)
more updates and tidied up main post
I've got my brand new Note 7 blocked by Samsung for almost 6 months, and change battery for the S7 version and Hydra Rom.
So far everything, I mean everything is working perfect! Iris, fingerprint, cameras, great sound and was able to install any app that I need so far. S-pen works great and if I charge 100% during the night (mobile data and wifi off, phone on) here's my day for test proposal:
7.00 am disconnect from mains and start wifi until 12:00 (several apps running, facebook , whatsapp, viber, phone calls and sms among others)
12:00 until 15:00 out of office mobile data on, wifi off.
15:00 until 19:00 wifi
19:00 until 00:00 wifi at home, games, facebook and whatever...
00:00 mobile data off, wifi off, phone on, don't charge.
7:00 same routine.
At 11:30, 12:00 it's at 10% battery.
So with the S7 battery on my Note 7 and Hydra I can get at least 20 hours regular use and 14 hours in standby.
I'm very pleased with this solution, I'm not an Adroid Update Maniac so this solution appears to be perfect to me.

i used some random flex cable i had laying around and a few matching connectors salvaged from dead motherboards, but as i pointed out i did that before resoldering old battery controller on the new battery and using that connector proved to be no good cos it didn't charged well and showed inaccurate capacity, etc., so i wouldn't recommend going that way
I don't have the note 7 battery controller
Someone had been using it ever since it got released, and 2 weeks ago his battery got bigger and had to remove it. He threw it all away. He gave the note 7 without the battery, thinking I could play around with it. Soy only chance of making this phone work again is if I use a note 8 battery.

Note8 or S7 OEM batteries are the same thickness as note7 (aftermarket chinesium ones can differ though), as for s9 or note9 batteries, those are considerably bigger in size, like shorter but much wider and so not usable in note7

well, any legit supplier had to pull out any note 7 batteries from being sold and note fe simply wasn't released as widely as note 7 or any other galaxy series phone, so most suppliers don't even have any parts for it, including batteries
