USDT TRC20 transaction failed due to insufficient energy

Question

I try to broadcast some USDT transactions every day, and after a few days, I receive OUT_OF_ENERGY messages for some transactions. I make some trades every day, sometimes I make about 30 trades. First, I tried staking about 20kTRX to gain energy and bandwidth, but it was not enough. When I triggered the transaction using a PHP script based on Trongrid documentation, it showed the fee limit as 10, so I increased the fee limit to 15TRX (15MSUN) but still no TRX was used to submit the transaction. But if I withdraw manually from TronLink wallet

I don't know if it is needed, but I found the solution this way. Function triggerConstantContract can return the energy consumption before the actual network call, but for some reason iexbase does not implement such logic. Therefore, I added my own function after the public function triggerConstantContract in TransactionBuilder.php which returns the complete result including energy information

public function triggerConstantContractFull($abi,
                                            $contract,
                                            $function,
                                            $params = [],
                                            $address = '410000000000000000000000000000000000000000')
    {
        $func_abi = [];
        foreach($abi as $key =>$item) {
            if(isset($item['name']) && $item['name'] === $function) {
                $func_abi = $item + ['inputs' => []];
                break;
            }
        }

        if(count($func_abi) === 0)
            throw new TronException("Function $function not defined in ABI");

        if(!is_array($params))
            throw new TronException("Function params must be an array");

        if(count($func_abi['inputs']) !== count($params))
            throw new TronException("Count of params and abi inputs must be identical");


        $inputs = array_map(function($item){ return $item['type']; },$func_abi['inputs']);
        $signature = $func_abi['name'].'(';
        if(count($inputs) > 0)
            $signature .= implode(',',$inputs);
        $signature .= ')';

        $eth_abi = new Ethabi([
            'address' => new Address,
            'bool' => new Boolean,
            'bytes' => new Bytes,
            'dynamicBytes' => new DynamicBytes,
            'int' => new Integer,
            'string' => new Str,
            'uint' => new Uinteger,
        ]);
        $parameters = substr($eth_abi->encodeParameters($func_abi, $params),2);

        $result = $this->tron->getManager()->request('wallet/triggerconstantcontract', [
            'contract_address' => $contract,
            'function_selector' => $signature,
            'parameter' => $parameters,
            'owner_address' =>  $address,
        ]);

        if(!isset($result['result'])){
            throw new TronException('No result field in response. Raw response:'.print_r($result,true));
        }
        if(isset($result['result']['result'])) {
            return $result;
        }
        $message = isset($result['result']['message']) ?
            $this->tron->hexString2Utf8($result['result']['message']) : '';

        throw new TronException('Failed to execute. Error:'.$message);
    }

}

So you can do something like this

$transfer = $this->_tron->getTransactionBuilder()
    ->triggerConstantContractFull(
        $this->abiData,
        $this->_tron->address2HexString($this->contractAddress),
        'transfer',
        [$this->_tron->address2HexString($to), $tokenAmount],
        $this->_tron->address2HexString($from)
    );
