[20.04.2010][v0.66] WMLongLife - Save your gonads (and battery) !
Note this is a BETA version and will have issues.
WMLongLife is an automatic 2G/3G band-switching solution. It will keep your device in 2G when you do not need to use 3G, and will switch to 3G automatically when you do need it. For most users, having your device in 2G uses much less battery, and thus your phone lasts longer on a single charge. 2G also usually generates less radiation than 3G, so it will likely be better for your gonads (if you have them) as well (see this thread
for a discussion about that
) - think of your hypothetical future children!
How to use
- 2G/3G (auto)/3G (only) automatic band switching based on:
- Running programs and their needs
- Availability of Wi-Fi
- Availability of USB
- Roaming [note: most roaming options have been removed, use the RoamFreely (marketplace) tool instead]
- Idle data connections disconnect based on running programs (note that unlike the registry tweak this does not break simultaneous voice/data)
- Manual band switching
- Automatically disable data when roaming (including AGPS)
- Pauses applications while switching bands (so you don't get networking errors)
- Several predefined applications supported
- Support for HTC/MSM72xx GSM devices (GSM/EDGE vs UMTS/HSDPA)
- Support for HTC/MSM75xx CDMA devices (1xRTT vs EV-DO)
- Support for various Samsung GSM devices (GSM/EDGE vs UMTS/HSDPA)
The manual is in the post below this one. Give it a quick skim!
You can use this yourself on your own devices, if-and-only-if you download it from this post. You are not
allowed to (re)distribute this app, not to your brother, not to your friends, not to anyone. Cooking it into your ROM and then distributing that is obviously also not allowed.
I reserve the right
to turn this into something commercial if I want. I'm not planning it, but lets just cut the crap and say it may eventually happen (avoid BS like the last time). Should that happen, as last time, people who helped out will get taken care of.
Is this guaranteed to save battery?
No, it is not. If it will or will not save battery is dependent on your configuration of WMLongLife, your 'average' network conditions, your radio, and usage. The default WMLongLife configuration will give you (also depending on those other factors) a nice average
between least and maximum savings while trying to be not too annoying. Radio firmware is very tricky, and results vary all across the board. It is likely there is a radio thread for your specific device, if you are comfortable with flashing devices, flashing a different radio may give you better (or worse) connectivity and battery life. How your usage effects all this should be obvious: if all you do with your phone is watch YouTube until the battery goes flat, WMLongLife will not help you [at all]. If you pretty much use at as a phone with additional email and some browsing / Google Maps here and there, you may definitely see benefits. It all depends.
Now let's get to the most interesting part: network conditions. 3G [at least in theory] uses less battery than 2G under ideal conditions. However, these ideal conditions are hardly ever reached. A lot of battery is spent finding a decent/better 3G signal to use instead of 2G - and I mean a lot
. If 3G is few-bars or just an unreliable signal in your area, your device will not just use a lot, it will use massive
amounts of battery trying to get a [better] 3G signal. Aside from that, if the conditions are less than ideal, 2G may
use less power than 3G. As an example, I am personally in an area with excellent
3G coverage (5 out of 5 bars of HSDPA) and my device still lasts nearly twice as long on a single charge with WMLongLife running. Your mileage may vary, of course. While it is completely possible that it may not make a relevant difference in your case, I would say there will be many people who this does make a difference for. This is also the reason you will see many people advising in "battery saving" threads to disable 3G and attesting to how much battery it saves for them, and others will always respond that it doesn't make a difference [for them].
Having an idle(!
) data connection should theoretically not make a difference with power usage, you have the connection anyway, it's just a question about whether you have an IP or not. However, some background applications (inside services mostly) will initiate data transfers if (and only if) a data connection is already up. So if you have an idle data connection, these applications would start using data, while if you did not have a data connection (connected), they would not.
