Bluetooth technology offers convenience - from hands-free phone calls to wireless file-sharing to playing music on a vehicle's speakers. But leaving your Bluetooth on all the time can be dangerous, and hackers are exploiting the technology to access private information, spread malicious software and more.
Most devices automatically shut 3G and 4G off when they are connected via Wi-Fi. When connected to a Wi-Fi network, the device will consume significantly less battery power. It's especially true with 4G, since the technology consumes a large amount of power.
13 tips to extend the lifespan of your phone battery

Even when connected to a Bluetooth LE (Low Energy) device that regularly communicates with your phone, such as a recently made fitness tracker, Bluetooth uses very little of your battery.
Bluetooth has proven to be an incredibly useful innovation that has enabled wireless connections between devices over short distances with minimal power consumption. However, some engineers have been working on a new Wi-Fi technology that could also replace Bluetooth while consuming even less power.
The maximum range for BLE wireless connections is 30 meters, while Wi-Fi goes further beyond. It depends on the version, but you can get well over 100 feet if you can extend the connectivity through external antennas.
A Bluetooth Classic device cannot communicate (directly) with a Bluetooth Low Energy device. Since many IoT systems involve small devices and sensors, BLE has become the more common protocol of the two (versus Bluetooth Classic) in IoT.
We estimate that a Wi-Fi router uses 2 to 20 watts, with 6 watts being average for a wireless router. Click calculate to find the energy consumption of a Wi-Fi router using 6 Watts for 24 hours a day @ $0.10 per kWh.
Bluetooth is a wireless method of transferring information from one device to another. In most cases, Bluetooth is more secure than Wi-Fi. As with any wireless system, though, your data may be transferred to others you did not intend to have access to your information.
“Bluetooth was borrowed from the 10th century, second King of Denmark, King Harald Bluetooth; who was famous for uniting Scandinavia just as we intended to unite the PC and cellular industries with a short-range wireless link,” he wrote in a column a decade later.
The official Bluetooth specifications state seven is the maximum number of Bluetooth devices that can be connected at once. However, three to four devices is a practical limit, depending on the types of devices and profiles are used.
To communicate between your devices, Bluetooth sends signals over a 2.4GHz radio frequency. Wi-Fi is perhaps the biggest and most problematic example, as are other Bluetooth receivers and devices, which can interfere with one another. That said, even microwaves can cause Bluetooth interference with your devices.
Bluetooth Internet Tethering
Internet via Bluetooth tethering is fast, but not as fast as compaired to the Wi-Fi Hotspot. Bluetooth 3.0 and Bluetooth 4.0 are said to have a similar device to device transfer speed of 25Mbps.Easy, simple setup
You'll only need one wire to connect the compact adapter to your A/V receiver or amp. You'll also have to plug the adapter into an AC outlet. Next, you enable Bluetooth on your phone or tablet and put it in pairing mode. Then you select the Bluetooth adapter from the onscreen menu.While Bluetooth devices may have Bluetooth baked in, sometimes a dongle is required. However, with 2.4Ghz wireless, a dongle is almost always necessary. It's a technology similar to Bluetooth, but with a proprietary radio frequency. Low-latency, high-quality audio comes from these chips, along with better battery life.
The rule is to keep your battery charged at somewhere between 40% and 80% level at all time. Overcharging, undercharging, extreme temperatures, these are all variables that can shorten the life of your lithium-ion battery (used in iPhones and Androids).
So having Bluetooth turned on, when you're not using a Bluetooth device, isn't going to drain your battery any more than having Wi-Fi on when you're not accessing the network. Yes, they may pull an insignificant amount of energy from your battery, but they will not drain it over the course of a day.
Do maintain your battery charge level between 40 percent and 80 percent. The ideal charge level for a stable battery is in the upper mid-range. Keeping a battery between 40 percent and 80 percent charged as often as possible will help you get the most out of its lifespan.
As soon as you notice your battery charge is dropping faster than usual, reboot the phone. Google services aren't the only culprits; third-party apps can also get stuck and drain the battery. If your phone keeps killing the battery too fast even after a reboot, check the battery information in Settings.
Essentially, keeping Bluetooth enabled on your phone at all times opens you up to potential hacks, abuse, and privacy violations. The solution is simple: Don't use it. Or, if you must, make sure to turn it off as soon as you've unpaired from the device in question.
Leaving your power saving mode on all the time limits the cpu speed, dims the screen and turns off syncing. So it cripples your phone, I rather carry an extra battery. If you set it to auto at least it won't come on until the battery is at 25%. It does not disable sync.
The main difference is that Bluetooth is primarily used to connect devices without using cables, while Wi-Fi provides high-speed access to the internet. Bluetooth is a wireless technology standard that is used to exchange data over short distances (less than 30 feet), usually between personal mobile devices.
If you're about to embark on a day-long trip and won't be around any Wifi for it, then yes, turning off Wifi will save your more battery, but there's no real need to shut it off if you're just going between one Wifi zone and another, such as between home and work or out to run some errands.

The answer to that is also yes, but it's negligible. Initially taken as a question of do the batteries in bluetooth headphones take more power than the batteries in wired headsets. The answer to that is yes, of course. Most wired headsets don't use batteries at all.
So having Bluetooth turned on, when you're not using a Bluetooth device, isn't going to drain your battery any more than having Wi-Fi on when you're not accessing the network. Yes, they may pull an insignificant amount of energy from your battery, but they will not drain it over the course of a day.
Turn your phone off completely
While it's true that turning on your phone uses more power than simply waking it from sleep mode, turning it off when you're not using it for hours at a time will conserve power in the long run.No, using Bluetooth doesn't count as data usage. However, if you're using an app that accesses data while using Bluetooth, you'll use data through the app.
