Fast answer: Nes. Yo. Well, it all depends... on how you use your device. Detailed answer Self-Experiment I just did a self-experiment to find out. Until now, I had all my devices fixed to 2G -- as that should "save juice", like the question suggests. So for 4 days now, I have 3G enabled. Surprisingly: No difference which could not be explained by ...

I think I already posted this in another answer -- but I don't remember where. As I think it where different details that time (more a general "what consumes most"), here some details from a reference Motorola Droid. Data taken from a German article named Energiesparplan (Heise is a very famous technology publisher in Germany; Google Translate Version here): ...

If you choose 3G only, you have no connectivity if you are in an area where no 3G is available. With 2G+3G, the phone will fallback to 2G if it can't get a 3G connection.

2G+3G is not recommended if you're in an area with spotty 3G coverage, as a radio switching back and forth will drain the battery much quicker. This is the major reason this widget option exists, to allow users to switch between 2G and 2G+3G on the fly.

No. This completely disables all data access. Only calls/messages can be used. EDIT: You might try looking into something called JuiceDefender. The free version will disable your data access when your screen turns off. Good for both battery saving and data-usage saving!

The generic perception is that networking via Wi-Fi cause less drain on your device's battery than connecting with 3G. During the data transfer, if you use both connections to perform the same download, you will find that Wi-Fi is more efficient since it transfers stuff faster than 3G, thus leading to less consumption of your battery. Rare exceptions may ...

Your understanding is correct. GPRS < EDGE < 3G < HSPA. HSPA = HSDPA (High Speed Downlink Packet Access + HSUPA (High Speed Uplink Packet Access) The difference between the three lies in the bands i.e. frequencies they use to communicate with the network. Edge uses the same frequency as the phone uses to transfer voice and SMS to the network. ...

The short answer is No, the baseband firmware is not for public usage (read carefully, I am referring to the programmatic details of this, i.e. API's) The baseband radio is isolated and proprietary and does not "exist" outside the realm of Android, rather, its using libraries which are closed source that interacts with the radio firmware. If you are ...

The radio frequency of a 2G radio operates in the range of 900 and 1800 MHz (source)- varying from country to country. The radio frequency of a 3G radio operates in the range of 2100 Mhz (source). As far as Samsung Galaxy Nexus LTE L700's specification is concerned, the 2G frequency is CDMA 800 / 1900, 3G frequency is CDMA2000 1xEV-DO and LTE (4G) ...

It differs with your connection quality, in normal situations Wi-Fi is faster. Wi-Fi mostly not usable for MMS, so you need to use e-mail.

2G consumes less power than WiFi when it comes to standard usage (surfing, small downloads etc). The problem with WiFi: It constantly scans for Hotspots even when you are connected to one and not using it. When it comes to big downloads etc, WiFi is more efficient. Reason: Due to slow speed, 2G will continue to drain battery for 2 hours when WiFi quits ...

For me switching to 2G has helped my battery last 2-3 hours longer. I use a samsung galaxy s3 I9300. Was using 3G connection for the first two months and the battery would be over by 14-15 hours under normal-heavy usage. Switched to 2G data couple of months back and the battery life has improved by 2-3 hours. My usage has always been the same with both 3G ...

With Xposed module and Gravity Box installed, the pull down status bar can be customised even on stock ROM (of course it has to be rooted). I have a Nexus 5 running stock 4.4.4 and following is how it looks: With these installed, one can swipe down with two fingers from top and just tap the last tile shown as "3G" in the image. Though this nearly misses ...

I've been looking for automated network switching for years, and I had always thought that this kind of behaviour was only possible using Cyanogen (or similar) ROMs. Anyway, I recently found some threads on XDA that suggest that this might not be true. First, it seems that in Sony Devices it's possible to tweak the system to show a 2G/3G toggle: ...

Use Wi-Fi. In most cases a Wi-Fi radio will offer greater bandwidth at a significantly lower battery cost. As a result, you should [prefer] Wi-Fi whenever possible. -- developer.android.com : Modifying your Download Patterns Based on the Connectivity Type via Transferring Data Without Draining the Battery.
